Disclosed is steering drive device for a pressing-controlled valve core, the steering drive device including a fixed top frame, a lifting drive rod, a vertical guide column, a lifting receiving seat, a fork-shaped swinging member, and a steering linkage. The steering linkage has an end that swings laterally when being moved, and the laterally swinging end is provided with a through hole for the fork-shaped swinging member to drive the swing arm, and cause the horizontal post to axially slide. The vertical cross-section of the through hole is rectangular, and the drive horizontal column has a range of up and down movement space in it, so that, when the drive swing arm generates lateral displacement due to vertical swing, it will pull the steering linkage along a circular path laterally moving, and at the same time drives the valve to rotate the actuating seat and cause it rotate laterally.

An automotive air control valve comprises a housing, the housing defining an air flow path, a blade pivotally mounted within the housing, the blade pivotable between a closed position, wherein the blade substantially blocks air flow through the housing, and an open position, wherein air can flow through the housing, an actuator adapted to selectively pivot the blade between the open and closed positions, a first stop that provides a positive stop for the blade when rotated to the open position, a second stop that provides a positive stop for the blade when rotated to the closed position; and an over-center cam mechanism, wherein the over-center cam mechanism is adapted to bias the blade in the open position when the blade has been pivoted to the open position, and to bias the blade in the closed position when the blade has been pivoted to the closed position.

A relief valve provides pressure relief when a fluid line exceeds a predetermined pressure. The valve includes a body which defines a cavity between inlet and outlet flowpaths. The valve includes a lever arm, which pivots around a pivot point as the valve changes between open and closed positions. A plunger assembly is disposed in the cavity and seals the cavity from the inlet and outlet flowpaths in the closed position. Fluid pressure from the inlet flow path causes the plunger assembly to contact the lever arm to urge the lever arm to rotate. The lever arm engages a spring at a further distance from the pivot point than the plunger assembly, the spring resisting pivoting of the lever arm and urging the valve to remain in the closed position unless a predetermined pressure is exceeded.

A rotatable pressure relief valve assembly is provided. The assembly may comprise a butterfly valve, a spring actuator, and a diaphragm device having a flexible membrane. A linkage assembly may be provided with a first end and a second end, wherein the first end may be configured to engage with a terminal end of a piston of a spring actuator, and wherein the second end may be configured to engage with a latch arm of the diaphragm device. A pilot tube may be configured to transmit an inlet fluid pressure from the inlet side of the butterfly valve to the sealed chamber. The assembly may further comprise a buckling pin mechanism having a buckling pin. The diaphragm device may be configured to translate the inlet fluid pressure into a compressive force and to transmit the compressive force to the buckling pin, and the latch arm may be configured to disengage from the second end of the linkage assembly when the buckling pin has buckled.

A fluid supply system for a machine such as an internal combustion engine includes a shutoff valve having an electrical actuator that includes a solenoid subassembly, and a stabilizer for the electrical valve actuator. The stabilizer includes a fitting structured to couple the shutoff valve to adjacent hardware in the fluid supply system, and a strongarm extending between the fitting and the solenoid assembly and clamped to the solenoid subassembly. A vibration-damping reinforced grommet may be clamped between the solenoid subassembly and the clamp.

A flow regulation device for liquid having a body with an inlet opening, an outlet opening, and a cavity between the two openings. An actuating means is disposed in the cavity for stopping and starting the flow of liquid through said device. The actuating means is configured to be moved in a first direction to start the flow of liquid through said device and in the first direction to stop the flow of liquid through said device. The actuating may comprise an upper button and a lower cam.

An automotive air control valve comprises a housing, the housing defining an air flow path, a blade pivotally mounted within the housing, the blade pivotable between a closed position, wherein the blade substantially blocks air flow through the housing, and an open position, wherein air can flow through the housing, an actuator adapted to selectively pivot the blade between the open and closed positions, a first stop that provides a positive stop for the blade when rotated to the open position, a second stop that provides a positive stop for the blade when rotated to the closed position; and an over-center cam mechanism, wherein the over-center cam mechanism is adapted to bias the blade in the open position when the blade has been pivoted to the open position, and to bias the blade in the closed position when the blade has been pivoted to the closed position.

Embodiments for an automatic fluid shut off device having a float disposed in a fluid catch basin attached to a first end of a flexible cable movable in an opposite direction of rising fluid in the catch basin; a second flexible cable end extending to a fluid supply base and terminating adjacent to a restrained spider assembly, the spider assembly configured to be rotationally displaceable upon a force by the second flexible cable end in response to a rising fluid in the catch basin; the spider assembly pivotably connected to a shut-off valve; and the shut off valve retained in an open position while the spider assembly is restrained, and under a rotational force to close the shut-off valve upon activation of the spider valve in response to the force by the second flexible cable end.

A valve assembly includes a ball configured to block fluid flow through the valve assembly while the ball is in a closed position and to enable fluid flow through the valve assembly while the ball is in an open position. The valve assembly also includes an actuator assembly configured to drive the ball to transition between the open position and the closed position. In addition, the valve assembly includes multiple compression springs disposed on one side of the ball. Each compression spring of the multiple compression springs is configured to directly urge the ball toward the closed position.

One or more techniques and/or systems are disclosed that can provide for a portable monitor control. A movement detection triggering system can be disposed between a fluid inlet and the body of the portable monitor, and may be able to restrict or reduce fluid flow when the monitor is moved from its desired position. A trigger arm can be coupled with the inlet, and, when the inlet is pivoted away from a set position, the trigger arm is also moved, which triggers another portion of the control system. A trigger pin is released, which may allow a lever to rotate, allowing a restrictor component to move into place in the fluid flow path, thereby restricting fluid flow.
