Inserted pressure regulating valve

Abstract

Disclosed is an inserted pressure regulating valve. A valve body is in a through hole structure, the end face of the bottom of the valve body utilizes a closing mode, a throttling block is inlaid at the bottom end of a valve hole of the valve body, a valve core is mounted in the valve hole of the valve body, a spring is mounted behind the valve core, a pressure regulating bolt and a locking nut are arranged behind the spring, and an outer cylinder of the valve body is provided with an O-shaped seal ring; and two groups of oil inlet holes A are arranged on the axial middle section of the valve body, a group of lubrication oil output holes C communicated with a lubrication oil way are arranged at a valve body orifice end, a group of radial oil return holes D are arranged between the throttling block and the oil inlet holes A, an induction hole B is arranged on the throttling block, the oil inlet holes A and the induction hole B are communicated with a control oil way, oil of the control oil way generates push acting force to one end of the valve core through the induction hole B and form a dynamic balance with acting force of the spring at the other end of the valve core, when oil pressure of the oil way is different, the valve core is placed at corresponding different positions and manages the opening degree between the oil inlet holes A and the lubrication oil output holes C, and the oil inlet holes A and the oil return holes D.

Description

1. Technical field [0001] The invention relates to a plug-in pressure regulating valve used in a hydraulic oil circuit of an automatic transmission of an automobile. 2. Background technology [0002] At present, the automatic transmission of automobiles has become one of the important directions of the development of automobile technology. Whether it is hydraulic AMT automatic transmission, AT automatic transmission, DCT automatic transmission or CVT automatic transmission, it is inseparable from the hydraulic control system. However, these hydraulic control system technologies are still in their infancy in China. In the process of product development, there is no ready-made pressure regulating valve to use. The design and development of each system has to develop a separate set of pressure regulating valves for the corresponding system. Judging from the current technical status, most of the pressure regulating valves use integrated control valves, and the function of the co...

AI Technical Summary

Problems solved by technology

[0004] The current control valves are all integrated on the system valve body, with complex structure and large size. The flow of the oil supply can not be limited, it can only be controlled by the switch of the oil circuit

For small systems that require control of small flow oil inlet and lubrication output flow, there is no ready-made pressure regulating valve to choose from
