Abstract: In an internal combustion engine with a reciprocating movement which uses gasoline, diesel fuel or other fuels to generate forces when fuels attain explosive combustion, the piston is pushed in the inner cylinder. The motion of the piston with the reciprocating movement (straight motion) is transferred to a crank shaft having rotation motion, or the rotation motion of the crank shaft is transferred to the piston having straight motion (reciprocating movement). By such transfer, in order to use in compressed feed for fluids, when the connecting rod is provided with a universal joint type and a ball joint type, although the relative position errors and right angle are staggered within a given range, abnormal friction, noises and vibrations never take place. Accordingly, pollutions such as noise, vibration and noxious exhaust gases are dramatically reduced, fuels are surprisingly and significantly saved, and the life of the machine is doubly increased. Further, the piston is divided into a crown part and a skirt part, and the crown part is used with a piston ring in a conventional way. However, the skirt part is attached to a metal roller mounted on a metal bracket, or a metal plate or spring, and the piston is provided with an expansion property. Accordingly, the gap or clearance between the cylinder and the piston is completely removed, and maximum smoothing motion takes place when the piston is moved up and down. By such smoothing action of the piston, a state without tilt and slap is realized.
Abstract translation: 在具有往复运动的内燃机中，当燃料达到爆炸性燃烧时，使用汽油，柴油燃料或其它燃料产生力，活塞被推入内筒。 往复运动（直线运动）的活塞的运动被传递到具有旋转运动的曲轴，或者曲轴的旋转运动被传递到具有直线运动（往复运动）的活塞。 通过这种转移，为了在流体的压缩进料中使用，当连杆具有万向节类型和球窝型时，尽管相对位置误差和直角在给定范围内交错，但是异常摩擦，噪声 振动永远不会发生。 因此，噪音，振动和有害废气等污染物大大减少，令人惊奇地，显着地节省燃料，并且机器的寿命增加了一倍。 此外，活塞被分成冠部和裙部，并且冠部以常规方式与活塞环一起使用。 然而，裙部附接到安装在金属支架上的金属辊或金属板或弹簧，并且活塞具有膨胀特性。 因此，气缸和活塞之间的间隙或间隙被完全去除，并且当活塞上下移动时发生最大平滑运动。 通过活塞的这种平滑作用，实现了没有倾斜和拍击的状态。

Abstract: An engine is disclosed having pistons in operative connection with a crankshaft. A bearing member, defining a curved periphery, is carried on the crankshaft for eccentric rotation thereabout in a direction transverse to the major axis of the crankshaft, with the periphery of the bearing member being positioned to be in power-transmitting, sliding relationship with a connection to the piston. The bearing member is adapted for transverse displacement by the piston rod relative to the crankshaft, while transmitting power to the crankshaft, to absorb any shock generated against the piston and the crankshaft, such as by "engine knock." The bearing member is also adapted for return to its predisplacement position after absorbing the shock.

Abstract: A valve actuator which employs a hydraulic cylinder for moving the valve element of a valve assembly. The piston and piston rod in the hydraulic cylinder are in abutting relationship. A convexly curved projection coaxial with the cylinder is formed on the piston for engaging a flat end surface on the piston rod. This arrangement minimizes the wear on the piston and, thus, increases the life of the hydraulic cylinder.

Abstract: A piston unit of a working cylinder has first and second coupling partners. The first coupling partner is a piston. The second coupling partner is a piston rod. The piston rod is inserted axially into the piston. Each of the coupling partners has an annular groove, the groove of the piston rod is an external groove, the groove of the piston is an internal groove. The grooves of the coupling partners lie opposite one another. The unit has a spring-loaded coupling ring. The coupling ring, when deformed in a tensioning direction, is fully accommodated by the groove of one coupling partner and which, when deformed in a release direction, engages in the grooves of both coupling partners. The engagement of the coupling ring in the grooves produces a form-locking connection between the partners. The piston rod is oversized in relation to the piston and provides an additional frictional connection.
