When the pressure to the brakes, the air compressor from lto promote the gas-liquid high-pressure gas4 gas piston master cylinder, gas piston and then push the oil piston. 当踩下制动踏板后,从空气压缩机l来的高压气体推动气液总泵4的气活塞,气活塞再推动油活塞。
It also provides a basis for solving gas blow-by and fuel leak between the piston and cylinder wall. 在实践和理论两方面为活塞环磨损开口间隙增大伴随的背间隙增大、侧间隙增大所致活塞与气缸壁窜气漏油问题提供了依据。
