The plunger is movably disposed within a plunger cavity that is defined by the base and the second annular wall. The cover is disposed on the housing. The valve body is connected to the housing. The valve body has an end wall that defines an outlet port, an annular wall that axially extends from the end wall and defines an inlet port, and a flange that extends from the end wall and engages the cover. The manual override unit is operatively connected to the plunger.

A fluid valve having a magnetic drive unit for a valve closing body is provided. The drive unit can have a core, a coil partially surrounding the core, and an armature which can be pivoted about a pivot axis by the energization of the coil and the resulting magnetic force, the valve closing body being in operative connection with the armature and being pivotable by the pivoting of the armature about a pivot axis and being positionable at least in a first and a second pivot position, and the valve closing body having a first and a second leg, the first leg extending into a valve housing having at least one fluid channel and the second leg projecting at an angle from the first leg and establishing the operative connection with the armature.

A valve housing for a fluid valve having at least one fluid channel through which a fluid can flow is provided. The valve housing can have a receiving space for a valve closing body movable in the valve housing, the receiving space having an opening, via which the valve closing body is introduced into the receiving space of the valve housing, and at least one first valve seat being formed in the receiving space and projecting into the receiving space in such a way that at least one undercut is formed in the receiving space by the first valve seat, and the valve housing being an integral injection-molded part, the at least one valve seat being produced integrally with the valve housing by an injection molding process.

A device for regulating the flow of a fluid comprises a valve housing having at least two valve ports, at least one valve seat, a valve member having a closing body, and an actuating unit for actuating the closing body. The valve member further comprises an actuation section, which is connected via at least one connecting web to the closing body for moving the closing body. A surrounding seal extends between the closing body and the actuation section, and separates the closing body and the actuation section from one another. The at least one connecting web is arranged such that the closing body is pivotable upon actuation of the actuation section by the actuating unit to move the valve member and thus the closing body relative to the at least one valve seat. The valve member is arranged to minimize, during the movement of the closing body, deformations in a passage area of the seal through which the at least one connecting web extends. A valve arrangement is provided with a respective device for regulating the flow of a fluid.

A device for regulating the flow of a fluid id formed with a valve housing having at least two valve ports. A first fluid path that extends between the at least two valve ports is formed in the valve housing. A first valve seat is assigned to the first fluid path. A first closing element is arranged to be coupled to the first valve seat to block or release the first fluid path, and an electromagnetic actuating unit for actuating the closing element. The actuating unit has a, first electromagnet and a second electromagnet that are coupled to the closing element via a coupling mechanism. The first and second electromagnets additively act on the closing element to displace the closing element between at least two positions.

A device for controlling fluid media, such as a directional control valve, includes a molded part made from an elastomeric material in which at least one line section is formed. The line section connects at least two connections to one another, between which at least one flow path extends. The device or valve has a control unit that includes an actuator coupled to at least one blocking element. The at least one blocking element is displaced by the actuator between a blocking position and a release position. In the blocking position, the at least one blocking element deforms the at least one line section in order to block the at least one flow path.

A valve includes a solenoid with a chamber housing a pin that actuates when the solenoid is energized. The valve also includes a spool housed within a sleeve. The sleeve includes a supply section with a supply port in communication with a supply source and a tank section with a tank port in communication with a reservoir. The spool includes a body including a first passage receiving fluid from the supply source when an opening for the first passage aligns with the supply port. When the solenoid is energized and the opening for the first passage aligns with the supply port, fluid from the supply source (i) applies a force to the spool body in a direction of actuation by the pin and (ii) flows to a second passage within the valve.
