A solenoid valve is formed by engaging locking protrusions with engagement holes and thereby joining a valve body and a magnetic cover to each other. A top wall of the magnetic cover is formed by a pair of bent portions that extend from a pair of respective sidewalls of the magnetic cover and that are bent toward the space between the sidewalls. The bent portions are fastened to each other in the width direction Wd by a circuit board spacer (first fastening member), and the circuit board spacer and the valve body are fastened to each other in the axial direction Ld by a connector cover.

A stepper motor driven actuator system is provided. The system includes a stepper motor, a cam, and a gearbox system. The gearbox system operatively connects the stepper motor to the cam. The cam rotates in response to stepping of the stepper motor. The system also includes a valve having a control piston located therein. The control piston is configured to translate in response to rotation of the cam. The system further includes a rotary actuator. The rotary actuator is fluidly connected to the valve, and the rotary actuator is configured to rotate the cam in response to translation of the control piston.

A valve having a metal insert with a fluid passage formed in the metal insert. A composite valve body is disposed at least partially around the metal insert and having at least one port in fluid communication with the fluid passage with the metal insert. A valve member is partially disposed in the metal insert and operable to control the fluid flow through the fluid passage of the metal insert and parts of the valve body.

A valve has a valve housing which is connected to an electronics unit. The electronics unit has an electronics unit housing which has an aperture in order to establish electrical contacting with an actuator of the valve. A portion of the actuator may protrude into the aperture. Here, play is provided between the aperture and the portion of the actuator.

A solenoid valve apparatus for a brake system for a vehicle, including: a main valve unit; a pilot-control valve unit that is fluidically connected to the main valve unit; and a housing to accommodate at least the main valve unit and the pilot-control valve unit; in which the pilot-control valve unit includes a double solenoid unit and at least one valve device, in which the double solenoid unit is formed such that it can be populated with at least one valve device, and in which the double solenoid unit has at least two accommodating portions for accommodating valve devices and at least two solenoid devices for actuating valve devices. Also described are a related braking system and a related method for mounting a solenoid valve assembly for a braking system for a vehicle.

The present invention discloses a movable valve core and an electromagnetic valve comprising the same. The movable valve core, comprising a cylindrical core body (1) defining a central axis, a leading head (2) fixed to the core body (1) removably, wherein a water-proof valve membrane (3) sandwiched between the core body (1) and the leading head (2), wherein a mounting hole (4) is axially formed in the core body (1), and a connector (5) for projecting into the mounting hole (4) extends axially from the bottom of the leading head (2), and the connector (5) is fixed into the mounting hole (4). The connector (5) is provided with an outer thread (6), and the leading head (2) is screwed into the mounting hole (4).

A valve having a metal insert with a fluid passage formed in the metal insert. A composite valve body is disposed at least partially around the metal insert and having at least one port in fluid communication) with the fluid passage with the metal insert. A valve member is partially disposed in the metal insert and operable to control the fluid flow through the fluid passage of the metal insert and parts of the valve body.

A spool valve arrangement comprising a spool arranged for linear movement within a bore to regulate flow of fluid through the bore according to the linear position of the spool relative to the bore, the spool having an end arranged to be engaged, in use, by a drive member to cause the linear movement, the spool valve arrangement further comprising a sliding block component moveably attached to the spool end and arranged to engage with the drive member, in use, such that the drive member engages with the spool end via the sliding block component and the sliding block component moves relative to the spool to compensate for non-linear movement of the drive member.

A valve with an electrodynamic actuator includes a magnet device that generates a magnetic field and a drive element that is movable relative to the magnet device. The drive element is pivotally mounted and comprises a current-carrying air coil that is arranged in the magnetic field and is fixedly coupled to a coil carrier made of a non-magnetic material. Sealing surfaces for sealing valve seats are arranged on two opposite sides of the drive element, such that the sealing surfaces face in opposite directions. A housing is comprised of a plurality of plastic housing parts and a metallic encasement. The metallic encasement surrounds an upper area of the housing in which the electrodynamic actuator is arranged and at least partially surrounds a lower area of the housing in which fluid channels are arranged.
