The invention belongs to the technical field of internal combustion engine accessories devices of engines and discloses a piston cooling nozzle device. The piston cooling nozzle device comprises a control valve body, a valve element, a spring, a limiting block, an oil spray pipe, positioning brackets and a plug. The control valve body comprises an oil inlet hole, an oil outlet hole and a cavity; the valve element and the spring are both located in the cavity, and the valve element is compressed at the junction of the oil inlet hole and the cavity by the spring at one end of the cavity; one endof the oil spray pipe is mounted on the oil outlet hole and communicates with the cavity of a control valve, the one or more positioning brackets are further arranged at one end of the oil spray pipe, and one or more oil spray holes are formed in a pipe body of the oil spray pipe; and an annular positioning groove is formed in the position, in the other end of the cavity, of the valve body, and the limiting block is fixedly mounted in the annular positioning groove. According to the piston cooling nozzle device, the component number is decreased, and the possibility of engine oil leakage is reduced; through the specificity of design of the oil spray pipe, interference of other parts in a cylinder body is effectively avoided; and through the open hole design, redundant heat of a heating part in the cylinder body can be effectively taken away, and the life of the engine is prolonged.
Description
technical field [0001] The invention belongs to the technical field of engine internal combustion engine accessory devices, and relates to a piston cooling nozzle. Background technique [0002] In the field of engine internal combustion engine accessories, high-performance diesel engines and gasoline engines have a large heat load. When the engine is working under high load, the temperature of the combustion chamber is high, and the piston is prone to overheating. The cooling method for the engine piston involves piston cooling nozzles. The traditional engine The piston cooling nozzle is composed of an oil bolt with a control valve inside, which is combined with a positioning pin, a sleeve and an oil injection pipe. It is installed at the bottom of the engine piston cylinder block, and oil is taken through the main oil passage on the cylinder block. There are many parts, the structure is complex, and the sealing effect between the main oil passage and the oil-through bolt is...
