A solenoid unit of an electromagnetic valve includes a coil, a bobbin, a fixed iron core, a movable iron core, an urging spring, a magnetic frame, and a molded plastic part. The magnetic frame includes a frame end wall, two frame arms, and an internal thread hole, to which the fixed iron core is threaded. A tubular projection protrudes from an end face of the frame end wall that is on a side opposite to the bobbin. The projection forms part of the internal thread hole. The molded plastic part includes a molded end wall, which covers the frame end wall, and a molded peripheral wall. The molded end wall includes a connecting hole that is continuous with the internal thread hole. The connecting hole includes a groove in an inner circumferential surface. The groove extends along an outer circumferential surface of the projection.

A portable oscillating compression system including an for compressing air; an accumulator tank for receiving and storing the compressed air from the air compressor; an air pressure adjustment module for modulating pressure of the compressed air when the compressed air exits the accumulator tank; a valve body assembly attached to the accumulator tank, a plurality of inflatable cuffs connected to the valve body assemble for receiving the compressed air from the valve body assembly; a controller for controlling the valve body assembly; a power supply; and a housing for containing said system.

According to one embodiment a valve arrangement for a gas burner is provided that includes a manual gas valve with a manual actuator for opening or closing the gas flow, and an electromagnetic valve having a movable closure member which allows opening or closing a gas passage to the burner. The electromagnetic valve is arranged in the gas valve, with the manual actuator being coupled to a rotary flow regulating element, the manual actuator being configured in order to move the closure member of the electromagnetic valve, opening the gas passage, the manual gas valve including a reduced gas flow channel which puts the inlet conduit in fluid communication with the regulating element regardless of the position of the closure member.

A valve drive with a snap function includes a rotary drive input, a lead screw connected to or formed by the rotary drive input, a slide in threaded engagement with the lead screw to form a screw thread, the slide being mechanically connected or connectable to a valve body and being movable in the direction of a longitudinal axis. A bearing housing is provided in which the lead screw is mounted so as to be rotatable about the longitudinal axis and stationary in the direction of the longitudinal axis. The bearing housing is held against a displacement along the longitudinal axis by a releasable locking device, countering the preload force of a snap spring.

A refrigerator appliance includes a water system. The water system has a fluid circuit and valve assembly. The valve assembly is configured to control flow through the fluid circuit. The valve assembly has a valve, at least one actuator disposed on the valve, and a framework configured to secure the at least one actuator to the valve. The framework has first and second upright members, a crossmember, and an electrical connector. The first and second upright members secured to the valve on opposing sides of the at least one actuator. The crossmember is secured to opposing ends of the first and second upright members relative to the valve such that the valve, first upright member, second upright member, and crossmember form a closed loop around the at least one actuator. The electrical connector is electrically connected to the at least one actuator and is secured to the crossmember.

An actuator mounting kit and method for mounting an automatic valve actuator to a manually operated valve. The mounting kit includes a mounting bracket and a stem driver. The mounting bracket is connectable to the valve and has a bottom portion with a stem aperture through which a valve stem is extendable and a tongue matingly engageable with a slot of the valve body. The mounting bracket has an upper portion with a driver aperture aligned with the stem aperture. The stem driver has a first end matingly engageable with the valve stem and a second end extendable through the driver aperture in a way that the actuator is matingly enageable with the second end of the stem driver when the actuator is connected to the upper portion of the mounting bracket.

A three way valve adapted to be connected to a water purifier includes a body, an inlet defined in the body for communication with a water source, a first outlet defined in the body to constantly communicate with the inlet, a waterway defined inside the body and between the inlet and the first outlet to communicate the inlet and the first outlet and a second outlet selectively communicating with the waterway. A solenoid valve is mounted to control the communication between the second outlet and the waterway so that pollutant screened by a filtering screen is flushed out from the outlet whenever water is flowing from the inlet to the outlet.

An assembly for actuating a double-acting shift cylinder of a shift assembly of an automatic transmission of a motor vehicle includes a hydraulic fluid reservoir having a motor-driven hydraulic pump and two control valves that are each connected to a pressure supply line of the hydraulic pump and to a return line to the hydraulic fluid reservoir. The shift cylinder has two pressure chambers that are each connected to one of the control valves. The control valves each connect one pressure chamber of the shift cylinder to the pressure supply line of the hydraulic pump or to the return line to the hydraulic fluid reservoir. The actuating assembly includes at least one pressure-limiting valve that connects the pressure supply line to the return line if a hydraulic over-pressure is present. The control valves can be 3/2-directional valves having integrated pressure-limiting valves.
