摘要： Disclosed herein is a master cylinder for a vehicle. The master cylinder includes a housing, a piston, inlet ports and a seal. The housing has therein a liquid pressure chamber to contain oil. The piston reciprocates in the liquid pressure chamber to control the pressure in the liquid pressure chamber. A front end of the piston has a stepped structure. The inlet ports are provided in the housing so that oil is supplied into the liquid pressure chamber through the inlet ports. The seal is seated into a seating depression which is formed in the inner surface of the housing. The seal opens or closes a flow path of the oil depending on whether the seal is brought into contact with the piston. The oil flows into the liquid pressure chamber along the stepped outer surface of the piston through a space defined between the piston and the seal.

摘要翻译： 这里公开了一种用于车辆的主缸。 主缸包括壳体，活塞，入口和密封件。 壳体中有一个液压室以容纳油。 活塞在液压室中往复运动，以控制液压室中的压力。 活塞的前端具有阶梯状结构。 入口端口设置在壳体中，使得油通过入口端口供应到液压室中。 密封件被安置在形成在壳体的内表面中的座位凹部中。 密封件根据密封件是否与活塞接触而打开或关闭油的流动路径。 油通过活塞和密封件之间限定的空间沿着活塞的阶梯状外表面流入液压室。
