摘要： A pneumatic control system is provided for selectively controlling movement of a pneumatically-operated device (20) between first and second working positions. The pneumatically-operated device (20) includes a working portion (30) and a pneumatic-control portion (32). The pneumatic-control portion (32) is in fluid communication with a pressurized fluid source (26) and includes a series of valves (64,66,70) for selectively manipulating the working portion (30) between the first and second working positions. The pneumatic-control portion (32) further includes a sensing system (56,58) for holding the working portion (30) in a static mode by selectively applying system pressure to the working portion (30). In this manner, a more energy efficient system is provided by eliminating the need for continuous application of full line pressure.

摘要： A hydraulic actuating device for a closure assembly, for example of a vehicle, which closure assembly comprises a closure element which can be moved between a closed position, in which the closure element closes off an opening, and an opened position.
The hydraulic actuating device comprises a hydraulic actuator (15) for moving the closure element, which actuator has a housing having a closing chamber (26) and an opening chamber (27). Further provided are a hydraulic pump (30) having an associated electric pump motor (31) and a reservoir (37) for hydraulic fluid.
The hydraulic actuating device further comprises a first pressure-limit valve (40), which is connected to the opening chamber (27), and a second pressure-limit valve (41), which is connected to the closing chamber (26). Control means (50) are further provided for controlling the supply of hydraulic fluid under pressure to the opening chamber (27) or to the closing chamber (26) of the actuator.
A hydraulic flow sensor (45) connected to the control means (50) is provided at each pressure-limit valve, such that the one or more hydraulic flow sensors detect the presence of a flow of hydraulic fluid through the pressure-limit valve to the reservoir.
The control means (50) are adapted - if a flow sensor detects a flow of hydraulic fluid - to reverse the supply of hydraulic fluid under pressure to the actuator, so that the opening motion is changed to a closing motion or vice versa.

摘要： This invention relates to a device for automatically switching discharge of pressurized fluid from outlet ports. To be more specific, this invention relates to an automatic pressurized fluid switching device for performing a switching operation using the pressure of pressurized fluid in itself without using electrical elements. An object of the invention is to provide an automatic pressurized fluid switching device having an excellent switching performance without using an electrical element so as not to be complicated in structure. To attain the object according to the invention, there is provided an automatic pressurized fluid switching device comprising an inlet port for introducing pressurized fluid, a plurality of outlet ports for discharging the pressurized fluid, a switching valve disposed between the inlet port and the outlet ports for switching over the outlet ports, a pilot valve for piloting the switching operation of the switching valve, and a reaction member for controlling the pilot action of the pilot valve in response to the pressure of the pressurized fluid introduced, which is characterized in that the pilot valve is provided with a first pilot unit in which the pilot action of the pilot valve is controlled only by the reaction member, and a second pilot unit in which the pilot action of the pilot valve is controlled by the reaction member in its initial and final stages and directly by the pressurized fluid in its middle stage. According to the invention, two lineages of the pilot action of the pilot valve for piloting the switching action of the switching valve can be constituted. The lineages are formed of the pilot action controlled only by the reaction member in the first pilot unit and the pilot action controlled by both of the reaction member and the fluid in the second pilot unit. The pilot action in the second pilot unit is controlled by the reaction member in the initial and final stages and by the pressurized fluid in the middle stage. Consequently, the pilot action in the second pilot unit in the middle stage can be securely effected even when the pressurized fluid introduced thereinto is little at the time of being again operated after stopping at the intermediate point of the switching action. Thus, smooth switching action can be performed securely.

摘要： Ein einfach wirkender Arbeitszylinder (1), der durch ein pneumatisches Druckmittel betätigt wird, ist mit einer selbsttätigen Rückstelleinrichtung versehen. Der im Zylin­derrohr (2) abgedichtet geführte Kolben (5) ist mit einer Kolbenstange (7) versehen, die aus dem Zylinderrohr (2) ab­gedichtet herausgeführt ist. Die Kolbenstange (7) besitzt einen großen Durchmesser, der nur wenig kleiner ist als der Durchmesser des Zylinderrohres (2), so daß um die Kolben­stange (7) herum ein Rückstellraum (12) gebildet ist. Au­ßerdem ist die Kolbenstange (7) hohl ausgebildet. Das so in ihrem Inneren vorhandene Rückstellvolumen (14) steht mit dem Rückstellraum (12) in Verbindung. Wenn der Kolben (5) mit Druckmittel beaufschlagt wird und seinen Arbeitshub ausführt, wird das Druckmedium im Rückstellraum (12) und im Rückstell­volumen (14) komprimiert. Sobald der Arbeitsraum (11) des Zylinders druckentlastet wird, bewirkt das im Rückstellraum (12) und im Rückstellvolumen (14) komprimierte Druckmittel eine Rückstellung des Kolbens (5) in seine Ausgangslage.
