Detailed Description
The invention is described in detail below with reference to the figures and the specific embodiments.
As shown in fig. 1a-1b, the oil-gas separation vent valve for the new energy electric bus with the oil piston machine comprises a vent valve lower cover 1, a vent valve upper cover 5 arranged in the vent valve lower cover 1 in a penetrating manner, and a vent valve spool 3 arranged in the vent valve upper cover 5 in a penetrating manner, wherein the vent valve upper cover 5 is arranged above the vent valve lower cover 1. The upper cover 5 of the ventilation valve is sleeved with an O-shaped ring 2, a first lubricating oil return cavity 7 is formed between the valve core 3 of the ventilation valve and the upper cover 5 of the ventilation valve, the O-shaped ring 2 is arranged on the lower portion of the upper cover 5 of the ventilation valve, and the O-shaped ring 2 is arranged between the upper cover 5 of the ventilation valve and the lower cover 1 of the ventilation valve.
