In a solenoid valve for a hydraulic braking system, a valve body has a receiving region which at least partially accommodates a guide assembly, the valve armature running axially through at least one through-opening of the guide assembly. A mechanical detent device is formed between the guide assembly and the valve armature, the detent device releasing the valve armature when the latter is in a de-energised closed position, such that the restoring spring drives the valve armature and pushes the closing element sealingly into the valve seat to produce a sealing function, and said detent device fixes the valve armature in a de-energised open position against the force of the restoring spring in an axial detent position, such that the closing element is raised from the valve seat.

A valve device has a valve housing (10), in which fluid ports (P, A, T) are provided and in which at least one valve piston (12, 14) can be moved longitudinally. The valve piston either separates at least two of the fluid ports (P, A, T) from one another or interconnects them as a function of its travel position. At least one latching device (16, 18) is provided for each valve piston (12, 14) for the detachable fastening of the respective valve pistons (12, 14) in one of its travel positions. Each latching device has at least one latching means (20), which can be brought into a latching position (22). As part of the respective latching devices (16, 18) for detachably fastening the respective valve pistons (12, 14), at least one control body (24) t can be moved independently of the respective valve pistons (12, 14), which control body is set up such that, in at least one blocking position, it prevents the relevant latching means (20) disposed in the latching position (22) from leaving the latching position (22) by blocking the latching means (20).

A pressure regulating shut-off valve has a valve member regulating flow of fluid between an inlet and an outlet. The valve includes a pneumatic actuator having a piston having first and second faces that define first and second volumes within a cylinder. The second face has a greater surface area than the first face. The first and second volumes are fluidly connected to the inlet, and an electrically actuated valve controls the flow of fluid along a fluid path to the second volume. The electrically actuated valve closes the fluid path, when power is supplied to the electrically actuated valve, and opens the fluid path, when power is removed from the electrically actuated valve, which causes the pneumatic actuator to act on the valve member to hold the valve member in a fixed position.

A fluid control device has a body, actuator, and slam-shut device. The body defines an inlet, an outlet, and a plurality of slam-shut openings, and a seat is positioned along a flow path between the inlet and outlet. The actuator is configured to modulate a position of a first control element relative to a first side of the seat along an actuation axis to control a fluid pressure. The slam-shut device has a second control element that is movable along the actuation axis and is biased toward a second side of the seat and a slam-shut actuator configured to trigger the second control element to move to the closed position in which the second control element contacts the second side of the seat. The slam-shut actuator includes a shaft and the slam-shut actuator and shaft are positionable in any one of the plurality of slam-shut openings in different configurations.

A valve includes a valve body forming a channel defining a fluid flow path extending from an inlet port to an outlet port of the valve body via a gallery disposed therebetween, an opening disposed in communication with the gallery, a valve assembly at least partially disposed through the opening and in the gallery, and a set pin having a central longitudinal axis. A valve disc of the valve assembly moves between a first position spaced from a valve seat of the valve body and a second position in contact with the valve seat. The set pin is coupled to and at least partly supported by the valve assembly to maintain the valve assembly in the first position. The fluid flow path allows a fluid to flow through the valve body in a first direction and a second direction opposite the first direction. The set pin is adapted to disengage a portion of the valve assembly when contacted by a fluid traversing the fluid flow path in the second direction, allowing the valve disc to move to the second position.

A switch valve for controlling a hydraulic fluid flow, the switch valve comprising: a capture element that is arranged in a valve housing and that is displaceable into a first switching position or a second switching position and interlockable by a spring loaded interlocking element in the first switching position or the second switching position, wherein a first hydraulic connection is connected with a relief connection in the first switching position and a second hydraulic connection is connected with the relief connection in the second switching position, wherein a switching travel of the capture element is limited, wherein the interlocking element is at least partially arranged in a recess of the capture element, and wherein the valve housing includes a first groove that is oriented in an axial direction and limited in the axial direction wherein the interlocking element is arranged axially movable in the first groove.

Electromagnetic gas valve with a gas inlet, a gas outlet, and a closure member that is displaceable between an opening position and a closing position. A maximum flow is supplied through the gas outlet with the closure member in the open position and a minimum flow being supplied with the closure member in the closed position. The valve includes a main fluid channel with a closure hole through which the maximum flow is supplied to the gas outlet. The closure member includes a secondary fluid channel calibrated for the minimum flow to pass therethrough, such that the closure member in the closed position covers the closure hole and allows the passage of gas through the secondary fluid channel.

The invention relates to a valve apparatus (10) for vacuum applications, comprising a valve housing (20) which delimits a valve chamber (22), the valve chamber comprising a vacuum supply opening (28), a suction opening (32), and a ventilation opening (36); comprising a valve body (40) which is arranged in the valve chamber and can be displaced along a switching axis (38) between a suction position and a ventilation position, wherein the valve body in the suction position closes the ventilation opening and in the ventilation position closes the vacuum supply opening; comprising a bistable actuator (50) for driving a displacement movement of the valve body, the actuator comprising an armature (52), connected to the valve body, and an electromagnetic coil (54) for driving a displacement movement of the armature; and comprising a swing check valve (74) for opening and closing the vacuum supply opening (28). The invention also relates to a vacuum handling apparatus (100) comprising a valve apparatus (10).

An integral flapper and nozzle structure for a servo valve assembly whereby the flapper, orifices and nozzles are formed by sheets of metal formed into a single component.

An air shutoff valve includes a passage for supplying air, a swing gate, a shaft attached to a reset handle, and a spring to urge the gate toward its closed position. A trigger assembly secures the shaft and gate in the open position and includes an actuator, a cam, and a rocker arm. A cam surface of the arm has a notch to receive a sear point of the cam. Movement of the handle against the spring causes the cam contact surface of the cam to follow the cam surface to cause the arm to rotate such that the sear point is received in the notch. Actuating the actuator causes the arm to pivot away from the cam such that the sear point is released from the notch, wherein the spring causes the shaft to move the gate to its closed position.
