  • Publication number: 20190032744
    Abstract: The application provides a damping adjusting system having a guide tube which is arranged in an outer housing and which comprises a lateral outer wall. The interior of the guide tube being delimited at the end face by a base part. The guide tube can also have a magnet coil; an electromagnetically movable armature which is guided in the guide tube along a movement axis; an exterior which surrounds the outer housing; and a ventilation bore which connects the interior to the exterior and which is guided through the base part and the outer housing. The ventilation bore has two interconnected sections. A first section is guided through the base part and the first section has a first opening arranged on the base part on the interior side and a second opening arranged on the lateral outer wall, and a second section is guided through the outer housing.

  • Patent number: 9551997
    Abstract: Electromagnetic fluid valve regulating the throughflow of a pressure medium which flows through a housing part having at least two inlet openings which lie opposite one another and at least one outlet opening for the pressure medium. It being possible for a channel which is situated between the inlet openings and the outlet opening to be closed to a greater or lesser extent by an axially movable slide for regulating the throughflow of the pressure medium, a pin protruding into the channel centrically with respect to the center axis of the fluid valve, the pin being provided, for flow guidance, with an outer contour which is of at least approximately conical, pyramidal or hyperbolic design, with the result that the pressure medium which is to flow from the inlet openings strikes the outer contour of the pin and diverted in the direction of the at least one outlet opening.

  • Publication number: 20150276084
    Abstract: The invention relates to a pressure control valve (1), comprising a valve body (2) with a control room (9) comprising a valve device (16) and a magnetic coil (4), with radially extending tank bores (20b) ending in the control room (9), an anchor (5), which is movable in an anchor chamber (6) by electrifying the magnetic coil (4), an anchor slide (7) guided by the valve body (2), which at one end is effectively connected to the anchor (5) and at the other end projects into the control room (9) of the valve body (2) to operate the valve device (16), whereby for the generation of pressure compensation, the anchor (5) is embodied between the anchor chamber (6) and the control room (9) with at least one axial pressure compensation bore (10), and the anchor slide (7) being supported in a bearing (8b) of the valve body (2) at the control room side showing at least one pressure compensation groove (14a, 14b).
