    摘要: The invention relates to a valve device (1), which has at least one manual, auxiliary actuating mechanism (25a, 25b), which contains a manually actuatable actuating mechanism (26a, 26bs), which can be locked releasably in the actuated state. A movable covering element (45) may be positioned alternatively in a release position, in which access to the actuating element (26a, 26b) is released, or in a covering position, in which access is prevented.  When the covering element (45) is in the locked state of the manual, auxiliary, actuating mechanism (25a, 25b), locking means (57) prevent it from being moved into the covering position.

    摘要: A closed loop hydrostatic transmission including a pump (11) having a charge pump (23) and an assembly (25). The assembly (25) includes a pair of relief and check valve assemblies (65,67), and each one includes a check valve poppet (71) relatively fixed to a washer member (83) in the absence of high pressure. The washer member (83) moves within a bore to define a chamber (85) in which is the spring (87) biasing the check poppet (71) closed. A drain valve (97) has its inlet in fluid communication with the spring chambers (85), and in response to a predetermined input, such as an electrical input signal (101), the drain valve opens (FIG. 3), and drains the chambers (85). In this condition, both check poppets (71) open, and fluid can flow freely within the closed loop so that, for example, the vehicle may be towed a short distance, without overheating the fluid, and without the need to mechanically unseat the check valves as has been common practice.

    摘要: The invention relates to an actuation device for a hydraulically controlled actuator (10), specially for the emergency operation thereof, comprising a housing (14) with a fluid container (16) which can be connected to the actuator (10) via a connection point (18) and to a hydraulic supply circuit (22) of said actuator (10) via another connection point (20). A separating piston (26) is guided lengthwise inside the fluid container (16) via a manually operated adjusting device (24). Said piston has a control device (28) for the through-opening (30) joining the connection points (18, 20) to each other. The inventive device provides an economical and simple way of reliably controlling and monitoring the hydraulically controlled actuator in case of malfunction by virtue of the fact that the adjusting device (24) is an adjustment screw (32) which can be screwed or unscrewed on the housing, the screwing path of which is chosen in such a way that the cooperating separating piston (26) can be displaced between two end positions (A, B) and that the through-opening (30) of the separating piston (26) has a flap valve (34) which is opened in either end position (A, B) and is closed in the corresponding opposite-lying end position (B, A).

    摘要: A three-position magnetic valve (10) has a double stroke magnetic system (16) set on one side of its housing (34) and manually controlled actuating means that consist of two actuating plungers (104, 106) whose individual displacement in the same direction allow the armature (17) of the double stroke magnetic system to be deflected in a controlled manner in opposite directions. A U-shaped guiding hoop (136) that projects into the inside (143) of the armature (17) is firmly anchored in the pole core (61) of the double stroke magnetic system (16) away from the valve. The guiding hoop carries a sliding supporting ring (126) on a section of its guiding shank (138) next to its yoke (144). The supporting ring (126) is held at a variable distance of one actuating element (106) by a pre-stressed compression spring (147) and at a fixed distance of the other actuating element (104) by a flexible supporting sheath (149) designed as a tension spring that surrounds the guiding hoop (136) with a close sliding fit. A compact emergency actuating device with a simple design is thus obtained.
