An electromagnet for producing a linear movement includes a housing, an exciter coil arranged in the housing, a pole core and an armature assembly, which is mounted centrally in the exciter coil and has a displaceable main armature and a displaceable armature disc. In the de-energized state of the exciter coil, an air gap is formed between the main armature and the armature disc and, The armature assembly has an elastic element, the preload force of which can produce an elastic force fit between the main armature and the armature disc in the energized state of the exciter coil in such a way that the armature disc is moveable towards the pole core, thereby producing the air gap, as soon as the magnetic force falls below the preload force. The electromagnet as an actuator thus acts alone with a defined spring preload and spring rate of the elastic element.

A pressure control valve for open-loop or closed-loop control of a pressure of a compressed fluid in a pilot pressure chamber includes a valve housing with at least one inlet and at least one outlet, a wall section fixedly connected with the valve housing and having a first passage channel and a first throughbore, through which the compressed fluid can flow, and forms a first valve seat. The pressure control valve also includes a tappet and first and second sealing elements. The tappet is mounted in the valve housing and movable along a longitudinal axis by an energizable actuation device. The first sealing element is mounted so as to be movable along the longitudinal axis in the valve housing and is biased by means of a first spring into a closure position in which the first sealing element bears against the first valve seat and closes the first through-bore.

A controllable shock absorber, in particular for motor vehicles, comprising a valve device comprising a bridge circuit with four non-return valves which are connected crosswise in the forward direction, the connection of a first bridge branch with two non-return valves that are arranged opposite each other form a pressure chamber and the connection of the second bridge branch with two non-return valves arranged opposite each other form a low pressure chamber, a hydraulic main slide arranged between the low pressure chamber and the pressure chamber, a pilot chamber which is connected to the pressurised fluid line which is part of the upper working space (traction area) by means of a fifth non-return valve, and a pilot valve which connects the low pressure chamber to the pilot chamber, the pilot chamber being connected to the high-pressure chamber by means of a diaphragm.

Controllable vibration damper

An electromagnetic switch valve for opening or closing an oil or coolant circuit in a motor vehicle, having an electromagnet, which has a coil and a movable armature, wherein the armature is coupled to a valve element, via which a valve seat in the coolant circuit can be sealed, wherein the switch valve is designed to be pressure balanced, and the valve element, pointing in the direction of the valve seat, is designed to be at least approximately hollow-walled.

The invention relates to a damping valve, in particular for shock absorbers of vehicles, with an adjustable damping force, in which differently sized outlet openings arranged between an inflow and an outflow can more or less be closed in order to obtain a desired damping effect. To this end, the differently sized outlet openings are more or less sealed off radially by means of a valve slide. In another embodiment, sudden pressure increases in the damping valve are automatically reduced by means of a differential area function. Due to said invention, said damping valve can be produced easily, has low leakage loss, a low tolerance chain and requires little effort for setting the desired damping.

A double-armature solenoid valve may include an adjustable first armature and an adjustable second armature arranged axially opposite each other along a common adjustment axis, and a coil mechanism configured to provide a magnetic flux. The valve may also include a first restoring spring, a second restoring spring, an inlet opening arranged on an axial side of the first armature opposite the second armature, and an outlet opening arranged on an axial side of the second armature opposite the first armature. The inlet opening and the outlet opening may be connected via a fluid duct. The first armature and the second armature may respectively have a different closing time such that when an energization of the coil mechanism is at least one of interrupted and reduced the inlet opening is closable more quickly via the first armature than the outlet opening via the second armature.

The invention is an electromagnetic valve, comprising

Electromagnetic valve

Electromagnetically actuable high-pressure valve, having a valve seat which is arranged in a valve chamber and which can be closed off by a sealing element and which is arranged between a low-pressure side (N) and a high-pressure side (H) of the valve, wherein the sealing element is arranged so as to be movable between an open position and a closed position, having a movably arranged armature, and having an electrically energizable coil which is designed and arranged so as to be suitable for acting on the armature, wherein the armature and the sealing element are arranged in the valve chamber.

High pressure valve

A high pressure control valve system with a valve body with an inlet and an outlet, whereby the outlet is shaped by at least one radially oriented opening in the valve body, an essentially discoidally shaped valve seat arranged on the valve body between inlet and outlet and features a valve body bore that connects inlet and outlet, a sealing element that is appropriately arranged on an actuating element in order to close the valve bore, and an actuating device suitably shaped to move the actuating element in such a way as to cause the opening and closing of the valve, characterized in that the valve seat on the exit site features a revolving extension, extending from a foot print axially in direction of the opening.
