Embodiment Construction
[0040] figure 1 : In the general view of the pressure compensation valve 1 , the first opening 8 , the second opening 10 of the valve housing 2 and a part of the piston 3 behind the second opening 10 can be seen.
[0041] figure 2 , 3 , 4 and 6: The support element 4 is placed in the valve housing 2 on the rear side of the pressure compensation valve 1 . The supporting element 4 is designed like a serrated ring and is elastic, distributed on the circumference of the base body 62, and has a plurality of serrated protrusions 28, which are axially fixed on the valve housing 2 in a form-fitting manner. Connector 63. Said form-fitting connection 63 consists of a protrusion 28 and a circumferential groove 21 , wherein the protrusion 28 engages radially in the circumferential groove 21 , ie snaps into place. Furthermore, the support element 4 is provided with a form-fitting element 22 in the form of a protrusion 25 passing through a recess 26 formed in the valve housing 2 (see i...

The invention relates to a valve (1) comprising a valve housing (2), at least one piston (3), at least one support element (4), and at least one spring (5), having the following features: the piston (3) and the valve housing (2) are arranged coaxially to each other on an imaginary valve axis (6), said valve axis (6) being oriented in a first axial direction and in a second axial direction opposite the first axial direction; the piston (3) is received in the valve housing (2) in an axially movable manner against the spring force of the spring (5), said spring (5) being supported on the support element (4) at least in the first axial direction and on the piston (3) in the second axial direction; the valve housing (2) is provided with a first opening (8) through which a fluid can flow and which can be closed by a piston base (7) of the piston (3); the valve housing (2) is provided with a second opening (10) which can be at least partly closed by a piston casing (9) of the piston (3) and through which the fluid can flow; and the piston casing (9) extends outwards from the piston base (7) in the axial direction of the support element (4) and surrounds the valve axis (6). The invention additionally relates to a method for producing the valve (20) and to a device (37) for regulating the pressure of a fluid in a vehicle transmission, comprising a valve (20) designed as a pressure compensation valve (1).
Description
technical field [0001] The invention relates to a valve with a valve housing, at least one piston, at least one support element and at least one spring, the valve having the following characteristics: [0002] the piston and the valve housing are arranged coaxially with each other on an imaginary valve axis, wherein the valve axis is directed in a first axial direction and in a second axial direction opposite to the first axial direction; [0003] the piston is accommodated in the valve housing to move axially against the spring force of the spring, wherein the spring bears on the support element at least in a first axial direction and on the piston in a second axial direction; [0004] the valve housing is provided with a first opening which is permeable to the fluid and which is closable by the piston seat of the piston; [0005] the valve housing is provided with a second opening at least partially closable by the piston housing of the piston and permeable to fluid; [00...
