The present invention provides a system for determining plunger position in a solenoid valve and method therefore. More specifically, the invention provides a solenoid valve having hall sensor for detection of plunger position, which provides feedback including output voltage (digital or analog) respective to its position. The solenoid valve includes a nozzle, a spring, a sealing rubber, a poppet, a magnetic bracket, a rubber grommet, a housing sub-assembly, a soft seal, a sensor assembly, a fix core, a moving core and/or plunger, coil, a bobbin sub-assembly, a fix core plate, magnet holder, a permanent magnet and plurality of terminals.

A valve (1) comprising a valve body (2) and a cartridge element (6), the valve body (2) having at least one seat (2A) configured to accommodate at least partially the cartridge (6), the cartridge (6) comprising an external surface (6A) configured to support at least partially an actuation element (12), said cartridge (6) containing at least one core (11) configured to cooperate with a nozzle (15) fluidly connected with a first fluid passage (3), said core (11) being movable inside said cartridge (6) against the action of an elastic element (14), between at least one first position in which it closes the first passage (3) and a second position in which it allows a flow through the first passage (3) so as to control the flow of a fluid through the valve; the valve comprises quick coupling means (200) for coupling to a support guide (201) of the valve (1).

To provide an electromagnetic valve capable of preventing damage due to stress of a buffer member. An electromagnetic valve includes a solenoid having a case, a flow path member, and a columnar valve element that is housed in the valve element housing portion of the flow path member and moves with a plunger of the solenoid to open and close a flow path. A seat member with which the plunger comes into contact is disposed in the case of the solenoid. The seat member includes a core portion with which the plunger comes into contact, and a plurality of protruding portions protruding radially outward from an outer peripheral surface on the radially outer side of the core portion.

A valve assembly includes a valve housing having a first port, a second port, and a third port. A valve member within the valve housing is moveable therein to alter fluid communication between the first and second ports. The valve housing includes a first annular groove such that a first sealing ring is provided in the first annular groove, thereby sealing the first port from the second port when installed in a receiving bore. The valve housing also includes a second annular groove such that a second sealing ring is provided in the second annular groove, thereby sealing the second port from the third port in the receiving bore. The valve housing also includes a first anti-tip flange extending radially outward to a greater extent than the first annular groove and a second anti-tip flange extending radially outward to a greater extent than the second annular groove.

An electromagnetic valve includes: a solenoid having a plunger movably supported along an axis O1 direction; a flow path member having a fluid passage flow path and a valve element housing portion; and a valve element in a columnar shape that is disposed in the valve element housing portion, is movable along the axis O1 direction together with the plunger, and can switch between an open state and a closed state. The flow path member has an abutment portion that abuts on the valve element in the valve element housing portion, and a biasing member that biases the valve element. The valve element has an enlarged-diameter portion on the radially outer side. The enlarged-diameter portion has an opposing surface portion opposing the abutment portion at least in the axis O1 direction. The opposing surface portion is in contact with the abutment portion in the open state.

An connecting structure of an electromagnetic valve includes: a first connecting structure body that prohibits a relative movement between a hydraulic pressure circuit body and an electromagnetic valve in an axis line direction; a second connecting structure body that prohibits a relative movement therebetween in a plane orthogonal to the axis line direction; a third connecting structure body that prohibits a relative rotation about the axis therebetween; and a connection body that is prohibited from moving relatively to the hydraulic pressure circuit body, wherein the first connecting structure body includes a first target connection tool that is provided in an accommodation body and a first connection tool that locks the first target connection tool in the axis line direction at a wall portion constituting an accommodation space.

A manifold includes a housing defining first and second inlets and outlets. With the housing, a valve retainer defines a first chamber in fluid communication with the first and second inlets. The valve retainer may engage a first valve assembly having a first actuator attached to a first valve member for regulating flow from the first outlet, and a second valve assembly having a second actuator attached to a second valve member for regulating flow from the second outlet port. A sensor assembly is configured to detect first and second operations of the first and second valve assemblies. A controller directs independent operations of the first and second actuators based on first and second flow rates derived from the first and second operations. The first and second valve members may be positioned within portions of respective first and second valve bodies in open fluid communication with the first chamber.

An actuator for a valve in an internal combustion engine includes an actuator housing, an electromagnet arranged in the actuator housing, the electromagnet comprising a yoke plate arranged at an axial end of the actuator housing, at least one clamping plate, and a sealing ring arranged at an axial side of the yoke plate facing the electromagnet. The sealing ring is pressed axially towards the yoke plate via the at least one clamping plate.

Embodiments of a solenoid valve are provided. The solenoid valve includes a solenoid portion having a housing. The housing has a first bore and a second bore with the first bore adapted to receive a first end of an armature assembly and the first bore being surrounded by a magnetic coil. The solenoid valve also includes a valve body. The valve body is adapted to receive a second end of the armature assembly. The solenoid valve further includes a detection device located in the second bore and a detection plate interposed between the solenoid portion and the valve body. The detection device interacts with the detection plate to produce a signal indicating whether the solenoid portion is installed on the valve body.

A valve cartridge for insertion into a valve block for a manifold valve for accommodating a valve in the valve cartridge includes at least one through opening for the passage of fluid flowing to the valve and a filter device for filtering the fluid. The valve cartridge includes a first part and a second part, which are interconnected in such a way that the through opening is formed by the first and second part, the filter device being arranged between the first part and the second part.
