    • A pump for a pressure washer. The pump includes a cam housing, a piston assembly disposed within the cam housing, a rotary shaft assembly disposed within the cam housing, a journal plate attached to the cam housing, a head assembly attached to journal plate and valve assembly operatively connected to the head assembly. The rotary shaft assembly includes a cam shaft, a vertically-extending oil tube partially disposed within a central portion of the cam shaft, a cam threaded onto the cam shaft and a thrust washer positioned adjacent the threaded cam. The piston assembly includes a plurality of pistons, preferably three, in mating contact with the thrust washer. Each piston includes a piston spring cap at one end, a spring disposed over the piston and engaging the piston spring cap, and a seal retainer having a low pressure seal at one end and a high pressure seal at the other end. The seal retainer includes an opening between the low pressure seal and the high pressure seal such that fluid passing through the high pressure seal is captured by the low pressure seal for recycling back into the head assembly. The head assembly, in combination with the valve assembly, forms a castellated assembly of a plurality of towers, preferably three, one for each piston. Each tower includes a low pressure valve assembly and a high pressure valve assembly that act as check valves. The low pressure valve assembly allows intake water to flow from the journal plate to a castellated tower channel. The high pressure valve assembly allows water to flow from the channel to the outlet fitting. The pressure washer can be mounted in either the vertical or horizontal orientation.
    • 用于压力清洗机的泵。 泵包括凸轮壳体,设置在凸轮壳体内的活塞组件,设置在凸轮壳体内的旋转轴组件,附接到凸轮壳体的轴颈板,附接到轴颈板的头部组件和可操作地连接到头部的阀组件 部件。 旋转轴组件包括凸轮轴,部分地设置在凸轮轴的中心部分内的垂直延伸的油管,与凸轮轴相连接的凸轮和邻近螺纹凸轮定位的止推垫圈。 活塞组件包括与止推垫圈配合接触的多个活塞,优选三个活塞。 每个活塞在一端包括活塞弹簧帽,设置在活塞上并与活塞弹簧盖接合的弹簧以及在一端具有低压密封件和在另一端具有高压密封件的密封保持器。 密封保持器包括在低压密封件和高压密封件之间的开口,使得通过高压密封件的流体被低压密封件捕获以循环回头部组件。 头组件与阀组件组合形成多个塔的雉形组件,优选地每个活塞为三个塔。 每个塔包括一个低压阀组件和一个作为止回阀的高压阀组件。 低压阀组件允许进水从轴颈板流到雉鸡塔通道。 高压阀组件允许水从通道流到出口接头。 压力清洗器可以垂直或水平方向安装。
