Problems solved by technology

[0002] At present, the oil pump is used as the pump for the delivery of lubricating oil of the engine. When it is working, it will generate a large pressure. Due to various reasons, the pressure in the pump will be too large. In order to prevent the damage of the pump body caused by the excessive pressure, And cause other accidents, a safety valve is usually installed on the pump body. When the pressure in the pump is too large, the safety valve opens, and the oil in the pump is discharged through the safety valve. The current safety valve is generally manufactured separately, and then installed in the On the pump body, the structure of the oil pump is complicated and maintenance is inconvenient

Abstract

The invention discloses a pump cover capable of installing a safety valve. The pump cover comprises a body in a shape of a flat plate. The body comprises an internal surface used for covering the pumpbody, the body is provided with a shaft hole and an oil outlet hole, the shaft hole penetrates the body, and the internal surface of the body is provided with an oil inlet cavity and an oil outlet cavity. The side face, perpendicular to the internal surface, of the body is provided with a safety valve body, the safety valve body and the body are integrally formed, a spring installation hole is formed in the safety valve body, one end of the spring installation hole stretches out of the safety valve body, the other end of the spring installation hole extends into the body and continues forminga valve ball section and an inlet section, and the spring installation hole, the valve ball section and the inlet section form a cavity used for installing a safety valve component. The oil outlet hole penetrates the oil outlet cavity and communicates with the inlet section. The valve ball section is provided with an oil leakage hole leading to the exterior of the body. The body and the safety valve body of the pump cover are integrally formed, the installation surface of equipment is reduced, and the installation precision of the safety valve is improved.

Description

technical field [0001] The invention relates to a pump cover of an oil pump, in particular to a pump cover capable of installing a safety valve. Background technique [0002] At present, the oil pump is used as the pump for the delivery of lubricating oil of the engine. When it is working, it will generate a large pressure. Due to various reasons, the pressure in the pump will be too large. In order to prevent the damage of the pump body caused by the excessive pressure, And cause other accidents, a safety valve is usually installed on the pump body. When the pressure in the pump is too large, the safety valve opens, and the oil in the pump is discharged through the safety valve. The current safety valve is generally manufactured separately, and then installed in the On the pump body, the structure of the oil pump is complicated and maintenance is inconvenient. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a pump c...
