Inlet air pressure adjusting type oil discharging device

Abstract

An inlet air pressure adjusting type oil discharging device in the technical field of mechanical design comprises an oil pump, a volume cavity, a movable body, a fixed body, an elastic component, a connecting pipe and an oil returning pipe. The movable body is arranged in the volume cavity and in contact with an inner wall face of the volume cavity in a sealing mode, the fixed body is arranged in the volume cavity and fixedly connected with the left wall face of the volume cavity, two ends of an oil inlet pipe are communicated with the rear end of a main oil channel and the lower wall face of the volume cavity, two ends of the oil returning pipe are communicated with the right wall face of the volume cavity and the lower wall face of an oil bottom casing, and the upper wall face of the movable body is connected with the upper wall face of the volume cavity through the elastic component. When pressure of the inside of the air inlet pipe of an engine is low, the movable body moves upwards, the main oil channel is communicated with the oil returning pipe, and the oil pressure of the main oil channel is reduced. When the pressure in an air inlet pipe of the engine is high, the movable body moves downwards, the main oil channel is separated from the oil returning pipe, and oil pressure of the main oil channel is increased. The inlet air pressure adjusting type oil discharging device is reasonable in design, simple in structure and suitable for the engine with a pressure increasing system.

Description

Technical field [0001] The invention relates to an oil supply adjustment system in the technical field of mechanical design, in particular to an intake pressure adjustment type oil drain device suitable for a supercharged engine. Background technique [0002] During the operation of the engine, oil plays a very important role. It can not only play a role in lubrication, but also play a role in sealing, cooling and buffering. When the engine is working, the speed is very high, and the piston and cylinder wall, connecting rod bearing bush and crankshaft are closely matched. If these matched parts are not sufficiently lubricated, dry friction will occur. The heat generated by dry friction in a short time is enough to melt the metal, causing damage to the mechanical parts (piston pulling cylinder, crankshaft holding bush, etc.), so good lubrication must be given to the matching parts of the engine. When the lubricating oil flows to the mating parts, it will form an oil film on the f...
