Embodiment Construction

[0012] The regulating valve 1 according to the invention has a housing 2 which is basically designed as a two-part housing. The upper part 3 has an electromagnetic drive unit 4 which acts on an armature 6 arranged in an axially displaceable manner in a bearing 5 . The electromagnetic drive 4 basically comprises a coil 7 , a core 8 and a magnetic flux guide comprising a return plate 9 and a yoke 10 . The housing made of plastic also has a plug 11 for controlling the pressure control valve. The core 8 is in this case clamped within the upper part 3 .

[0013] The electromagnetic driver 4 acts on the armature 6, which in this case serves as the valve stem and valve closing member of the on / off valve. The armature 6 is here pretensioned in the closed position relative to the core 8 by means of the spring 12 . The spring 12 is guided by a peg 13 which, in the installed state, is arranged adjustably in the core and at the same time serves as an upper stop element for the armature...

Abstract

The invention relates to a pressure control valve having a housing, which has a coil wound on a coil carrier, an armature that is axially displaceable in a bearing, a core and a flux guiding device, and which has a connecting bore and a connector, wherein the connector has a valve seat for the armature, wherein the housing is substantially implemented in two parts, wherein a bottom part has the connector and the connecting bore and is arranged in a force-locked or form-fitting manner in a top part of the housing, wherein a bearing bushing for the armature is provided in the part of the connector directed toward the core, and a stop bushing for the armature is provided in the opposite part of the connector.

Description

technical field [0001] The present invention relates to a pressure regulating valve with a housing, the pressure regulating valve having a coil wound on a coil former, an armature movable axially in a bearing, a core and a magnetic flux guide, and the pressure The regulating valve has a connecting hole and a connecting head, wherein the connecting head has a valve seat for the armature. Background technique [0002] Such pressure regulating valves are used in particular in hydraulic regulating devices, in the control of automatic transmissions of automobiles, or also in combination with pressure- or flow-controlled engine oil pumps. Here, the pressure regulating valve may be a so-called on / off valve or a so-called modulating valve capable of steplessly regulating the flow rate. For example, the on / off valve known from DE 197 16 185 A1 is mentioned here. Here, the electromagnetically driven armature cooperates with the valve seat to fluidly communicate the connection openin...
