Abstract

The invention provides an engine. The engine comprises an engine body, an engine oil cooler and an engine oil cooler cover; the engine body is provided with a main oil duct and a first oil duct; one end of the engine oil cooler communicates with the first oil duct, and the other end of the engine oil cooler communicates with the main oil duct; the engine oil cooler cover comprises a first cavity, the engine oil cooler cover is fixed to the engine body, and the engine oil cooler is located in the first cavity; and the engine oil cooler cover is provided with a second oil duct, the second oil duct comprises a first oil port and a second oil port, the first oil port communicates with the first oil duct, the second oil port communicates with the main oil duct, a control valve is arranged between the first oil port and the second oil port, and the control valve is opened when the pressure of engine oil in the second oil duct reaches a rated value. According to the engine, the control valve and the second oil duct are integrated on the engine oil cooler cover, a hydraulic control oil way is simplified, the stability of an engine hydraulic system is improved, effective operation of the engine is guaranteed, and the reliability of the engine is improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic control, in particular to an oil cooler cover integrating a control valve and an oil passage. Background technique [0002] In the prior art, in order to ensure the stability of the engine hydraulic system and ensure the effective operation of the engine. The oil cooler assembly includes a base for fixing the oil cooler, the control valve and the oil passage are integrated inside the base, and the base is fixed to the machine body. The outside of the oil cooler also needs to be provided with a seal for the oil cooler cover, and the oil cooler cover is fixed on the base. In other prior art, the oil cooler can also be fixed on the oil cooler cover through threaded connection. The oil first enters the oil cooler cover, and then enters the oil cooler. After cooling, it returns to the body through the oil outlet channel in the oil cooler cover. The oil circuit is complicated. [0003] The above-me...
