    • A log splitter (10) includes a pump (24) connected to a hydraulic reservoir (30) and an elongated beam having a splitting wedge and a support plate mounted thereon. A hydraulic ram (22) provides relative motion between the wedge and the plate to split logs. The ram (22) includes a cylinder (50), a piston positioned within the cylinder, and a piston rod (52) reciprocally movable within the cylinder. The hydraulic ram also includes a control valve (62) connecting the pump and the cylinder. The first end collar (54) includes a first cylinder head and a valve body of the valve (62) cast as a single component. The valve body defines an inlet port (70), an outlet port (72), an "A" port and a "B" port. The second end collar (56) includes a second cylinder head and defines a channel fluidically connected to the "B" port. The first and second cylinder heads are sealingly held on ends of the cylinder with tie rods (58).
    • 对数分配器(10)包括连接到液压储存器(30)的泵(24)和安装在其上的分离楔和支撑板的细长梁。 液压柱塞(22)提供楔形件和板之间的相对运动以分裂原木。 冲头(22)包括缸(50),定位在气缸内的活塞以及在气缸内可往复运动的活塞杆(52)。 液压压头还包括连接泵和气缸的控制阀(62)。 第一端部轴环(54)包括作为单个部件铸造的阀(62)的第一气缸盖和阀体。 阀体限定入口(70),出口(72),“A”端口和“B”端口。 第二端部轴环(56)包括第二气缸盖并且限定流体连接到“B”端口的通道。 第一和第二气缸盖通过拉杆(58)密封地保持在气缸的端部上。
