A valve comprising a housing, a solenoid in the housing, a pin that can be moved by the solenoid, and a cup-shaped piston connected to the pin. The piston has an injection-molded membrane as a base, and the pin is connected to the membrane. The valve further includes a spring that rests against the membrane. The membrane is riveted to the pin.

A solenoid valve for the automotive industry includes a housing comprising an inlet channel and an outlet channel. An electromagnetic circuit is arranged in the housing. The electromagnetic circuit includes a coil wound onto a coil carrier, an armature, a core, and a return device. The armature and the core are arranged in a valve interior. A valve rod is arranged to adjoin the armature. The valve rod is movably mounted in the core via a bearing. A sleeve body seals the valve interior. The sleeve body is provided as a bearing element for the armature. A valve closure body is operatively connected to the armature. The valve closure body includes pressure equalization openings and is movably mounted in the sleeve body via a first sealing element. A spring pre-tensions the armature.

A control valve (1) for a camshaft adjustment device, and to an internal combustion engine having a camshaft adjustment device and a control valve (1) is provided. The control valve (1) includes a valve housing (3) and a pressure medium guiding insert (23) arranged coaxially in a recess of the valve housing (3). A discharge passage (27, 28) of the pressure medium guiding insert (23) transitions into a discharge duct (22) running in the axial direction, wherein the discharge connection T can be connected to the control connection A, B and wherein the discharge connection T is arranged in a region between the second end (8), which is opposite the first end (6), and the control connections A, B.

A metering valve comprising a solenoid having: a coil mounted on a core; and an armature moveable axially with respect to the core and against a return bias in response to a current in the coil; a variable capacitor having a first plate mounted for movement with the armature and a second plate fixed with respect to the core. The metering valve comprises an electronic feedback loop which is used to adjust the current in the coil based on a feedback signal derived from of the capacitance of the variable capacitor. A reference capacitor may be provided having opposing third and fourth plates at a set separation. A valve body may house the solenoid, the variable capacitor and the reference capacitor.

Examples are provided that describe a linear hydraulic valve. In one example a linear valve comprises a sleeve with a plurality of ports spaced apart from each other at a distance. The plurality of ports are associated with a plurality of pressurized fluids. A spool comprising a plurality of openings that correspond to the plurality of ports is provided within the sleeve. The plurality of openings are spaced apart in a manner that enables alignment of a given opening of the plurality of openings to a given port of the plurality of ports based on a given position of the spool within the sleeve. The linear valve comprises an actuator for moving the spool in a forward or reverse linear motion along a longitudinal axis of the sleeve. The spool may be moved to a given position based on selection of a pressurized fluid of the plurality of pressurized fluids.

A fluid control valve includes a valve main body and a vibration sensor. The valve main body has an actuator section and a valve section. The sensor detects vibration generated in the valve main body. The vibration is generated by a water hammer phenomenon. The water hammer phenomenon generates impact when the valve element comes into contact with the valve seat and no fluid leaks between a valve element and a valve seat. The fluid control valve further includes a controller to execute an abnormality determining program and determines the valve main body to be normal when the sensor detects the vibration with an amplitude exceeding the predetermined threshold, while determines the valve main body to be abnormal when the sensor does not detect the vibration with an amplitude exceeding the predetermined threshold.

A setting adjustment tool for a magnetically adjustable device implanted in a patient includes a circumference. A plurality of magnetic coils can be circumferentially distributed on a circumference of the tool. One of the magnetic coils can be movable along the circumference between a plurality of predetermined positions associated with the selectable performance settings. The magnetic coils may also be capable of attracting or repulsing the at least one magnet of the rotor of the implanted device in a radial direction by at least a predetermined angle within a plane of rotation of an at least one magnet of the rotor thereby inducing a rotating moment into the rotor.
