    Nhrs2Yet another specific object of the present invention isthat the tool / aid can only be disconnectedthe safety valve when it is closed, ie. the hose tothe tool / aid is depressurized.
    Another specific object of the present inventioninvention is that there is a venting of the pressure in the hoseto the tool / aid in connection with the safety valvecloses.At least the primary purpose of the presentinvention is realized by means of a device which has obtained the ithe following independent claim 1the features. Preferred embodiments of the invention aredefined in the dependent claims.
    Brief description of the drawingsHereinafter, an embodiment of the invention willdescribed with reference to the accompanying drawings, in which:Fig. 1 shows a schematic section through the safety valveaccording to the present invention when the safety valve isclosed;Fig. 2 shows a schematic section through the safety valveaccording to the present invention when the safety valve isopen; andFig. 3 shows a schematic section through the safety valveaccording to the present invention when the safety valve isduring transfer from open to closed position.
    Detailed description of a preferred embodiment ofthe inventionThe safety valve shown in Figs. 1-3 according tothe present invention comprises a valve housing 1, whereinthe longitudinal direction of the valve housing 1 is defined by the double arrow L iFig. 1.provided with a continuous channel 12, the channel 12A ball-shaped element 11 is arranged in the valve housing 1one end is widened by means of one formed in the element 11bevel 10. The ball-shaped element 11 is rotatable about oneaxis of rotation 6. The valve housing 1 is also provided with avent hole 9 extending from the sphericalseat 11 of the element to the outside of the valve housing 1.
    W3The safety valve of the present inventionalso includes an outlet for the pressure medium, thisoutlet according to the embodiment shown consists of a fromvalve housing 1 projecting nipple 13 as exv. a quick coupling4 can be connected to. A hose 14 or the like is connected tothe quick coupling 4 and the hose 14 from the quick coupling 4 turnend is connected to any / any of the kitchen utensils / utensilsthat the user has. As an example of such utensils canmention various print media-driven hand tools / aids, e.g.whisks, dish brushes and root brushes etc .. At the end ofthe valve housing 1 facing away from the nipple 13 is an inlet 15 forthe pressure medium is arranged, this inlet 15 being onlyschematically shown as it can be designed in many ways.
    The inlet 15 is designed so that it via a hose (not shown)or the like can be connected to a print media sourceThe safety valve of the present invention(not shown).also includes a carriage 2 which at least partially surroundsvalve housing 1. The carriage 2 is displaceable relative to the valve housing 1in the longitudinal direction of the valve housing 1. The distance that sled 2 isdisplaceable relative to the valve housing 1 is denoted by D in Figs.The safety valve of the present invention comprises1 andFig. 1shiftalso a spring 8 which is arranged between the valve housingslide 2. When sliding slide 2 to the left inthe spring 8 is compressed, the spring 8 striving tothe slide 2 to the right in Fig. 1. The slide 2 comprises two pins 7,see Fig. 2, which are arranged in connection with the carriage 2left end in Fig. 2. Pins 7 extend towards each other inthe carriage's 2 interior space.
    The safety valve of the present inventionalso includes a knob 3 as shownthe embodiment surrounds the valve housing 1 on three sides, i.e. angry3 comprises two side walls 20 and a back portion 21 whichconnects the side walls 20. The back portion 21 has an extentwhich are generally perpendicular to the side walls 20, which aremutually parallel. The ball-shaped element 11 is torsionally stablethe connection with the knob 3 and the axis of rotation 6 is common tothe ball-shaped element 11 and the knob 3. This means that thenthe knob 3 is rotated to carry the spherical element 11. AsAs can be seen from Fig. 1, the spherical element 11 is located inU4a closed position when the back portion 21 assumes a vertical position,i.e. a position where the back portion 21 has an extension transverselylongitudinal direction of the safety valve L.
    Each of the side walls 20 included in the knob 3has a recess 5, see Fig. 2, this recess 5 beinglocated essentially in the same plane as the back portion 21. Where andone of the recesses 5 is intended to cooperate with an associatedpin 7 and in Figs.sampled 5.1, the pins 7 are included in the associatedThe safety valve of the present inventionworks as follows. When the knob 3 engages in Fig. 1shown position, the valve is closed, ie. the spherical elementll prevents flow through the valve body 1. When the quick coupling 4connected to the nipple 13, there will be an offsetleft in Fig. 1 of the carriage 2 because the correct engagement betweenthe quick coupling 4 and the nipple 13 require the carriage 2 to be imparteda shift to the left in Fig. 1. The size of thisdisplacement is denoted by D in Fig. 1.
    In Fig. 2, a satisfactory connection has been established betweenthe quick coupling 4 and the nipple 13. The one thus generatedthe displacement of the carriage 2 means that the pins 7 are no longerincluded in the recesses 5. Thus, the knob 3 can be turned,to that shown in Fig. 2the position and the spherical element ll is brought to it inpreferably manually by the user,Fig. 2 showed the position, i.e. the channel 12 assumes a position whichenables flow through the safety valve according to the presentinvention. Pressure medium can thus flow offthe source of pressure media, through the safety valve and on to theutensils to which the hose 14 is connected. In the mode thatthe knob 20 in Fig. 2 prevents access of the quick coupling4, i.e. the user can not disconnect the quick coupler 4 whenthe safety valve is open.
    When the user wishes to change implements, it is appropriateto first close the safety valve according to the presentinvention. In FIG.safety valve. The knob 3 has been turned from the position according to Figs.2 in the direction of the arrow P, see Fig. 3. When the knob 3 has occupied it3 shows an intermediate position of the knob 3 ofThe position shown in Fig. 3 is the passage through the safety valveturned off and the connection to the source of pressure media, via the inlet, is off. The pressure remaining in the hose 14 is dissipatedat the position shown in Fig. 3 via the chamfer 10, the channel 12and the vent hole 9. The knob 3 is then turned further sothat it occupies it in FIG.
    When the hose 14 is depressurized, the connection between1 showed the situation.the quick coupling 4 and the nipple 13 are separated without the risk ofquarterly pressure in the hose 14 poses a problem, ie.the quick coupling 4 is displaced to the right in Fig. 3. The carriage 2is thereby displaced, by the action of the spring 8, to the right in fig.3 and the pins 7 are received in the recesses 5, i.e. that shown in Fig. 1the situation has been reached again.
