Description

Novel engine oil check valve structure

Technical Field

The utility model relates to the field of check valves, in particular to a novel engine oil check valve structure.

Background

One-way valves, also known as check valves or non-return valves, are used in hydraulic systems to prevent reverse flow of oil flow or in pneumatic systems to prevent reverse flow of compressed air. The structure of the one-way valve is generally sealed with the sealing surface of the valve body through a steel ball.

At present, one part of common one-way valve products is formed by plastic, the durability is poor, the risk of cracking and leakage easily occurs, and the other part is a machined forming part, so that the quality is high, and the light weight requirement cannot be met.

Disclosure of Invention

The utility model aims to overcome the defects in the prior art and provide a novel engine oil one-way valve structure.

The utility model provides a novel engine oil check valve structure, includes annular disk seat, annular disk seat intra-annular on set up the valve gap, valve gap and annular disk seat's upper surface between set up the sealing washer, the lower extreme of valve gap set up the draw-in groove on joint part and the U type spring holder and buckle and be connected, U type spring holder and annular disk seat between set up return spring.

The novel engine oil one-way valve structure disclosed by the utility model has the advantages that the oil inlet direction is transferred to the press mounting direction, so that the novel engine oil one-way valve structure meets the use requirement of a more complex oil way, and the novel engine oil one-way valve structure is simple in structure and convenient to install.
