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.
