A method for manufacturing a hydraulic device is described, in which at least one hydraulic channel and at least one connection are manufactured and/or hydraulically connected to one another, the hydraulic device being manufactured from at least two plates, and the plates being formed and connected to one another with the aid of the processes of cold forming, deep drawing, punching, punch riveting, and/or clinching.

In a hydraulic unit, which is for a hydraulic brake system, that has a hydraulic block and at least one valve device, the valve device includes a hydraulic cartridge with a valve seat and with a movable closing body for blocking and opening the valve seat, and a magnet assembly with a magnet coil for generating a magnetic force for moving the closing body. The magnet assembly is integrated into the hydraulic block, and the valve device has a permanent magnet in order to assist the movement of the closing body by means of magnetic force.

A cryogenic cylinder control system for regulating fluid within a cryogenic cylinder is disclosed. The system includes a pressure relief and vent module fluidly connectable to a head space above liquid within the cryogenic cylinder, a manual valve module fluidly connectable to the liquid within the cryogenic cylinder and to an external device, a solenoid valve module fluidly connectable to the manual valve module and to the head space within the cryogenic cylinder, a build-up coil fluidly connectable to the manual valve module and to the solenoid valve module, and a controller operatively connected to the solenoid valve module to control fluid flow through the solenoid valve module.

This EGR valve system is provided with a valve assembly, and a plurality of housing adapters. The valve assembly is provided with a housing including a flow passage, a valve seat provided in the flow passage, a valve element provided in the flow passage in such a way as to be capable of seating against the valve seat, a valve shaft on which the valve element is provided, and a driving unit for driving the valve shaft. The housing adapters include assembly holes, inlet flow passages which communicate with the assembly holes, and outlet flow passages. One of the housing adapters is selectively combined with the valve assembly, the housing of the valve assembly is assembled in the assembly hole of the selected housing adapter. In this assembled state, the inlet flow passage communicates with an inlet port, and the outlet flow passage communicates with an outlet port.

A method for producing one or more concave cut-outs on a main body, which is in particular substantially cylindrical, more particularly one or more grooves on a magnetic armature, a push rod, or a magnetic keeper plate, includes the following steps: providing a main body, which is in particular substantially cylindrical and has a first axis of rotation, rotating the cylindrical main body around the first axis of rotation in a first rotational direction by means of a lathe, and rotating a striking tool, which is provided with a number of fly cutters, around a second axis of rotation, which extends in parallel and offset in relation to the first axis of rotation in a second rotational direction, which is opposite to the first rotational direction, in such a way that the fly cutter engages in a material-removing manner in the main body to produce the cut-out.

A modular valve for free-flowing media, with a main module with a valve housing and an electromagnet, a dosing module with a closure member which is movable by means of the electromagnet and which closes a dispensing opening of the dosing module, and a valve lift adjustment module for adjusting the valve lift, which valve lift adjustment module comprises an elongate abutment part which is arranged at least in part in a valve interior of the main module and is modifiable in its axial position in the valve interior, which abutment part limits the movement of the closure member in the direction of the valve lift adjustment module, the dosing module and the valve lift adjustment module being connected releasably to the main module in such a way that the dosing module and the valve lift adjustment module can each be replaced by another module of the same module type.

A valve includes: a housing; a solenoid arranged in the housing; a pin movable by the solenoid; and a pot-shaped piston connected to the pin. The solenoid has a coil body having a central opening, an upper stator arranged in the central opening, and a lower stator configured to receive the coil body. The pin is mounted in first and second bearings arranged in the upper stator and a bushing, respectively. A guide sleeve is arranged at least in the central opening of the coil body, and the upper stator and the bushing are arranged in the guide sleeve.

Embodiments of a solenoid valve are provided. The solenoid valve includes a solenoid portion with a detection device, a valve body, an armature assembly, and a detection plate. The armature assembly has a first end extending through the solenoid portion and a second end extending into the valve body. The detection plate is configured to interact with the detection device to produce a signal indicating whether the solenoid portion is installed on the valve body. The solenoid portion is disposed between the valve body and the detection plate.

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.

A valve assembly includes a valve body having a fluid inlet and a fluid outlet. An operator cavity is within the valve body, and the valve body includes a valve operator socket surface. A valve operator is slidably coupled with the valve body and in the operator cavity. The valve operator includes an operator surface configured to selectively isolate the fluid inlet from the fluid outlet, and an end surface. At least one of the valve operator socket surface or the end surface of the valve operator include a discontinuous interface. The discontinuous interface includes a recessed surface, and one or more interface breaking projections extending from the recessed surface, the one or more interface breaking projections space the recessed surface from the valve operator socket surface.
