摘要： A sanitary insert part includes an insert housing, which includes in a housing interior thereof a functional element that controls throughflow and that has at least one throughflow orifice. At least one throughflow opening is delimited by a peripheral wall, the shape of which can be changed against a restoring force as a result of the pressure of the inflowing water in such a manner that the at least one throughflow orifice has a variable orifice cross section which can be changed, in dependence on the pressure of the inflowing water, between an open position and a minimized position having a reduced orifice cross section by comparison.

摘要： There is provided a very reliable three-way solenoid valve that can reliably switch a refrigerant flow passage while ensuring a refrigerant flow rate even under a large-differential pressure environment without increasing the size of an electromagnetic coil and the like.A valve body includes a conduction hole that communicates with a back pressure chamber formed on a side of a second valve element opposite to a second valve seat, a third valve seat that is positioned between the conduction hole and a second outlet, a third valve element that is movably disposed so as to approach and be separated from the third valve seat, a coil spring that biases the third valve element toward the third valve seat, and actuating rods that are interposed between a first valve element and the third valve element.

摘要： A hydraulic soft-start system includes a first flow valve in fluid communication with a pressure source and an inlet of a motor. A first restricting orifice is disposed between the first valve and the inlet. A second flow valve is in fluid communication with the first valve and the inlet. A pilot for actuating the second valve is in fluid communication with the inlet. A second restricting orifice is disposed between the pilot and the inlet. Upon actuation of the first valve, a first flow is passed from the pressure source via the first orifice to the inlet, placing the motor in a partially-actuated state. The second valve being actuated after a threshold pressure of the pilot is reached allowing a second flow to pass from the pressure source to the inlet. The second flow being higher than the first flow, thereby placing the motor in a fully-actuated state.

摘要： What is disclosed is a pilot-controlled pressure feed valve comprising a main stage and a pilot control stage, wherein the main stage comprises a piston that is biased into a closed position. The piston is provided with a piston bore through which an input port may be connected with a rear-side spring chamber. To this piston bore a throttle valve means is associated which provides a comparatively small cross-section of flow for the control oil in the pressure limiting function of the pressure feed valve, and a comparatively large cross-section of flow in the anti-cavitation function.

摘要： An automotive vehicle includes a vehicle body and at least one reservoir containing a fire suppressant agent. A distribution system receives the fire suppression agent from the reservoir and conducts the agent to at least one location about the vehicle's body in response to the determination by a sensor system and controller that the vehicle has been subjected to a significant impact. The reservoir includes a discharge port controlled by a piloted spool valve actuated by pressure generated by a propellant device.

摘要： A valve arrangement in a hydraulic circuit comprises a longitudinal duct 3 and a transverse duct 2. A throttle slide 10 can be displaced in the direction of the longitudinal duct 3. Arranged in the throttle slide 10 is a valve piston 25, by means of which the flow through the hollow throttle slide 10 can be enabled or blocked. The flow of hydraulic fluid takes place through two groups of passage holes 33a, 35a, which are arranged in the throttle slide 10. The interaction of pressure and flow direction of the hydraulic fluid, and also the restoring force of a slide spring 20 and a piston spring 30, achieves a situation where hydraulic fluid can flow through the valve arrangement in both directions but that a throttling action occurs only when the hydraulic fluid flows from the transfer duct 2 to the longitudinal duct 3 under increased pressure.
