    Abstract: A valve structure includes: a valve unit including a valve body, a shaft portion extending from the valve body, and a separating portion provided on the shaft portion and spaced apart from the valve body; a mounting plate located between the valve body and the separating portion and including an insertion hole into which the shaft portion is inserted; a holding portion including a first holding surface provided on the mounting plate, and a second holding surface provided on the valve unit and spaced apart from the first holding surface; a protrusion provided on one of the valve unit and the mounting plate, an end of the protrusion protruding beyond the first and second holding surfaces; and an elastic body including a contact portion located between the first and second holding surfaces, and a pressed portion located inside or outside the contact portion and contacting the protrusion.

    Abstract: An inline variable sonic valve is provided that includes a housing defining an inlet and an outlet positioned inline along a gas flow axis. A contoured metering plug is fixed within the housing and a diverging sleeve is movably positioned within the housing downstream of the contoured metering plug. An actuator is positioned offline from the gas flow axis and is configured to move the diverging sleeve within the housing relative to the contoured metering plug fixed therein to vary a gas metering area defined between the contoured metering plug and the diverging sleeve. The actuator may be hydraulic, fueldraulic, pneumatic, or electric, and may drive the diverging sleeve discretely to an open or a closed position, or to a variable position between the open and closed position when a position senor is included to meter the flow therethrough.

    Abstract: Example aspects of a sliding disc assembly for a dual spring valve, and a method of operating a dual spring valve are disclosed. The sliding disc assembly can comprise a shaft defining a first end and a second end; a disc mounted on the shaft between the first end and the second end, the disc defining an upper disc surface, a lower disc surface, and an annular base surface; a first spring mounted on the shaft between the lower disc surface and the first end of the shaft; and a second spring mounted on the shaft between the upper disc surface and the second end of the shaft, wherein the first spring defines a spring force that is different from a spring force of the second spring.

    Abstract: A valve (1), in particular a piston valve, including a stationary housing part (2) and an actuating element (3) which can be adjusted relative to the housing part (2) and is in, or can be brought into, an operative connection with a valve body (4). The valve body (4) can be adjusted by way of actuation of the actuating element (3) between an open position which opens an outlet (5) and a closed position which closes the outlet (5). The valve (1) has a damping device (6) for extending a closing time of the valve (1), by an adjusting force which is applied for the closure of the valve (1) being opposed by a damping force which is produced by way of the damping device.

    Abstract: An actuator includes a housing defining an inlet port, a piston and a return spring disposed within the housing, and an elastically deformable element. The return spring is configured to apply a biasing force to the piston to move the piston to a spring return position. A first fluid pressure applied to the inlet port moves the piston against the biasing force of the return spring to a first actuated position in which the piston indirectly engages a stop portion of the actuator housing. A second fluid pressure, greater than the first fluid pressure, applied to the inlet port moves the piston against the elastically deformable element to compress the elastically deformable element to move the piston to a second actuated position beyond the first actuated position.
