AI Technical Summary

Technical Problem

Existing fluid pressure regulation devices face challenges in precise alignment of transversely oriented openings with channels during assembly, leading to potential misalignment and reduced fluid flow.

Method used

The device incorporates an annular gap around the valve with a reinforcement and seal, allowing for flexible positioning of transverse openings relative to channels, and uses a reinforcement to maintain sealing integrity under pressure.

Benefits of technology

Ensures reliable fluid flow by maintaining alignment and sealing despite pressure variations, simplifying assembly and reducing manufacturing complexity.

Abstract

Device (1) for regulating pressures of a fluid in a component (4), wherein the device (1) is formed at least by the component (4) and at least one valve (3), and wherein the valve (3) has an axially aligned valve axis (2) and is at least partially seated in the component (4) and has at least one opening (16), wherein the opening (16) opens into an annular gap (21) at least partially surrounding the valve (3), and wherein the annular gap (21) is formed between the valve (3) and the component (4), wherein the annular gap (21) is sealed with at least one seal (5), wherein the seal (5) is formed at least from a sealing ring (28) and a reinforcement (27), wherein the reinforcement (27) is designed to be rotationally symmetrical about the valve axis (2) and at least a part of the reinforcement (27) surrounds the annular gap (21) at least partially in the radial direction, iealigned transversely to the valve axis (2), covered, characterized in that a leg (29) of the reinforcement (27) at least partially radially covers the annular gap (21), wherein a sealing ring (28) axially supported by the leg (29) axially closes the annular gap (21) running axially parallel to the valve axis (2), and wherein the reinforcement (27) has a hollow-cylindrical collar (33) which is formed integrally with the leg (29) and which is at least radially guided on a hollow-cylindrical neck (19) which is aligned axially in the direction of a first channel (18) and formed around the valve axis (2) on the valve (3) and delimits an opening (15).
