    • 专利摘要:
    Control valve devices, in particular for antilock device on pneumatically operatable vehicle brake systems, have a controllable inlet valve (47, 2) and a controllable outlet valve (9, 10). A pressure medium output chamber (3, 7) can be connected via the inlet valve (47, 2) to a pressure medium intake chamber (48, 50) and via the outlet valve (9, 10) to the atmosphere. …<??>Since, in normal operation (uncontrolled operation), the reduction in pressure in the pressure medium output chamber (3, 7) occurs via the inlet valve (47, 2) and the pressure medium intake chamber (48, 50), the reduction in pressure is considerably delayed. …<??>In order to overcome this disadvantage and to shorten the times taken for the reduction in pressure, the pressure medium intake chamber (48, 50) is subdivided into a first sub-chamber (48) connected to the inlet valve (47, 2) and a second sub-chamber (50) connected to the pressure medium intake (39), as shown in fig.1. The first sub- chamber (48) and the second sub-chamber (50) can be connected to one another via an additional valve device (38, 42) designed as a non- return valve directable onto the first sub-chamber (48) into the open position. …<??>By this measure it is ensured that in the event of a reduction in pressure the return flow of pressure medium from the pressure medium output chamber (3, 7) occurs not via the pressure medium intake chamber (48, 50) but via the outlet valve (9, 10) directly into the atmosphere, thereby resulting in an accelerated reduction in pressure in the pressure medium output chamber (3, 7) and hence in the consuming unit. …<IMAGE>…

    Claims (6)
    [1]
    Claim
    1. The control valve assembly, in particular for an anti-lock 45 system of pneumatic brake devices of vehicles, comprising an inlet chamber of a working medium communicating through an inlet with a source of a working medium connected to a consumer and an outlet chamber of a working medium communicating through a controlled inlet valve with a working inlet medium, and through the exhaust valve, it is controlled by an executive piston with the atmosphere, and the executive piston is installed with the possibility of impact on the exhaust valve in the direction of its closure under the action of pressure in the control chamber, selectively communicating with the atmosphere or with the inlet chamber through a control valve, characterized in that, in order to improve operational characteristics, the inlet chamber of the working medium is divided into first and second sections communicating through a check valve the locking element which is mounted to move to the opening position in the direction of the first section under the influence of pressure in the second section, the first section being in communication with the inlet th valve, the second section is with the input of the working medium, and the control valve is connected to the second section.
    [2]
    2. The node under item 1, characterized in that the check valve is made with a throttle.
    [3]
    3. The node according to claim 2, characterized in that the non-return valve is made of a damper located in the first section, installed in the area of the through hole, made in the wall of the node housing and connecting the first and second sections of the input chamber of the working medium.
    [4]
    4. The node under item 2, characterized in that the check valve is made in the form of a spring-loaded. a pore element mounted on a saddle defining a passage opening connecting the first and second sections of the input chamber of the working medium.
    [5]
    5. The node according to paragraphs. 1, 3 and 4, which includes the fact that the inlet valve is controlled by an actuating piston made in the form of a membrane clamped into the housing of the assembly and secured with a part of the outer edge portion in the area of the passage opening, which serves to connect the first section to the second section of the chamber a working medium, the check valve being formed by the edge section of the passage opening facing the first section and a shutter, which is fixed at one end to a part of the membrane support.
    [6]
    6. The node according to 2, characterized in that the check valve is made in the form of a damper and interacting with it facing the first section of the working medium chamber of the edge portion of the passage opening connecting the first and second section of the working medium chamber, the shutter being attached at one end to a pin, installed in the node body in the first section, and the main part of the cross-section of the passage hole is blocked by a shutter.
