    A high pressure spraying gun has a jet pipe, a pressure water supply element, two trigger levers for right-handed and left-handed actuation, and only one blocking valve arranged to selectively block and to release pressure water through flow through the jet pipe or through the pressure water supply element and including a valve body, a spring which biases the valve body in a first direction, and a rocking member having two ends spaced from one another in a second transverse direction, so that the blocking valve can be opened only under the simultaneous action of two trigger levers on both ends of the rocking member.

    movements of the spring of the balancer 17, having end sections 23, 24 for each of them to open the shut-off valve with the supporting surface of one of the two trigger arms or with the supporting surfaces of the actuated components of the trigger arms. The smallest distance between the supporting surfaces of the release levers or the powering of the trigger arms in the safety position and the axis 16 of the balancer rotation is greater than the greatest distance between the end portions 23, 24 of the balance weight and its axis 16 turns. The balance bar is provided with a triggering protrusion to hold it in the safety position of the trigger arms c. starting position. The triggering projection is made in the form of a spring-loaded coil spring 20 of the bolt 18, adjacent one end to the balance weight 17, and the other to the coil spring. The bolt 18 and the screw spring 20 are installed in the sleeve 19. When both trigger arms are simultaneously actuated, the supporting surface 25 of the lever rod 11, which moves under the action of the first trigger lever in the longitudinal direction of the valve body 4, acts on the end portion 24 of the ball 17; a supporting surface 26 acts on the opposite end portion 23 of the balancer. 11 Cf f-crystals, 4 silt,
    The invention relates to a spray technique and can be used to clean surfaces with pressurized water.
    The purpose of the invention is to facilitate the handling and increase the reliability of

Figure 1 shows a high pressure spray gun, longitudinal section; in fig. 2 - a fragment of the spray gun in the area of the gate valve; in fig. 3 points} 1sir when operating with only one discharge lever, inoperative position; in fig. 4 - balancer, when only BTOpi iM is operated with a drain lever, second non-working position,
    The spray gun (Fig. 1) has a nozzle I for supplying water by pressure, to which the string pipe 2 adjoins. Between the water supply nozzle 1 and the spray pipe 2 a shut-off valve 3 is installed, the body 4 of which is loaded with a compression spring 5. The spray gun contains the drain arms 6 and 7. The drain lever 6 is fixed to rotate on the swing axis 8 and through the pusher 9 is connected to the coupling 10, which in turn is connected to the lever rod 1 1, which reaches the gate valve section 3. The coupling 10 is mounted on the jet pipe 2 and the opposite pusher 9 with the end rests on the compression spring 12, which is also mounted

    It is mounted on the jet tube 2 and rigidly fixed in the housing 13.
    The second drain lever 7 is also held with pressure, namely the compression spring 14, which rests on the handle 15 on the one hand, and on the other hand on the drain lever 7,
    FIGS. 1 and 2 depict the position of a check valve in which none of the drain levers 6 and 7 are actuated.
    At the free end of the body 4 valves, t, e. On the opposite end of the jet tube 2, which is made in fork of the present example, between the shoulders of the plug is installed with the possibility of rotation on the bolt 16, the balance weight 17.
    On the side opposite to the valve body 4, the balancer 17 rests on the end of the bolt 18 installed in the sleeve 19, and the other end of which forms the bearing surface for the screw spring 20, which is fixed in the sleeve 19 by means of a screw 21 without a head. The spring force acting through the bolt 18 on the balance weight 17 in the unloaded condition effectively and permanently holds the balance weight 17 in a certain position, therefore non-controlling rotation is excluded.
    The sleeve 19 with its protruding shoulder abuts against the bottom of the sleeve 21, inside which spring 5 is placed, with one end resting; ts into the bottom of the sleeve
    21 from the inside and the other end into the end of the screw 22.
    The balancer 17 has annular portions 23 and 24 for engaging with the bearing surfaces 25 and 26 of the lever rod 11 connected to the clutch 10 and, accordingly, the lever 7.
    A safety clip 27 is attached to the front of the spray gun.
    The spray gun works as follows.
    For safety reasons, the activation of the high-pressure spray gun is only possible when two discharge arms 6 and 7 simultaneously operate, one with the left and the other with their right hands. When only one bleed lever 6 or 7 is actuated, the shut-off channel 3 remains closed and the flow of water through the nozzle and, accordingly, the blast tube 2 is blocked. ,
    When simultaneously actuating a freewheel 25, it is effective to prevent the release arms 6 and 7 from the supporting surface 25 of the lever rod AND, which is moved by the action of the drain lever 6 in the longitudinal direction of the valve body 4, to the end portion 24 of the balancer 17, and the opposite end portion 23 of the balance bar 17, the supporting surface 26 acts.
    With simultaneous use of the support surface 25 of the lever rod 11 and the support surface 26 and the end sections 24 and 23 of the balancer 17 is in the equilibrium position, therefore the valve body 4 can move in
    axial direction, namely, overcoming the force of the spring 5, which rests on the bottom of the sleeve 21.
    When the valve body 4 is axially moved, the path between the pressurized water supply tail 1 and the jet pipe 2, which was closed by the shut-off valve 3, is released and free flow is possible.
    If only a hand-50 is operated, and in the safety
    To one discharge lever 6 or 7, as shown in FIG. 3 and 4, the balance weight 17 is loaded on one side and does not serve to transfer the force and, thus, to move the valve body 4 longitudinally, therefore the shut-off valve 3 remains closed.
    FIG. 3 shows the position of the balancer 17 when actuating the leverage of at least one pull-down lever, the flow through the branch pipe into the appropriately branch pipe is closed, characterized in that, in order to facilitate handling and increase the reliability of operation, the blocking means is made in the form of sharn but in the valve body transversely from

    Chaga 7, in which the lever rod. turns the balance weight 17 around the bolt 16. On the other hand, the distance on the outer edge of the balance weight 17 from the bolt 16 is less than the smallest distance of the end surface 26 of the lever 7 from the bolt 16 of the balance weight 17, in particular in the initial position of the lever 7.
    10 The same applies to the distance of the outer edge of the end y4act 24 of the balancer 17 to the shortest distance of the bearing surface 25 of the lever rod 11 from the bolt 16.
    15 Oe, Tim ensures that the balancer 17 moves freely, KOI-yes only one descending lever 6 and 7 is activated and, thus, safety measures are not taken.
     Actuation of only one release lever 7 is shown in FIG. 4, which clearly shows that the balancer 17 is tilted in one direction and as a result of the described
    the unlocking of the valve 3 rotates due to the axial movement of the valve body 4.
    As can be seen from FIG. 1, the front discharge lever 6 with safety clip 27 advantageously has the ability to at least partially rotate around the spray pipe 2. This measure provides equal opportunity to control the high-pressure spray gun with both the right and left primary working hand.
