摘要： A rotary piston engine with external combustion/expansion chamber is disclosed. According to an aspect, a rotary piston engine includes an intake cylinder/piston block to press air/medium toward a combustion/expansion chamber. The cylinder/piston block includes cylinders, pistons and piston rods. Connected to the cylinder/piston block is a converter wheel, which converts piston movement to rotation of the converter wheel and rotation of the cylinder/piston block. The rotation angle of the converter wheel is different than that of the cylinder/piston block such that the distance between pistons and converter wheel varies according to the displacement. The piston rods are able to displace at the converter wheel in 2 different directions, both going around the converter wheel and sideways compared to the converter wheel. The cylinder/piston block and the converter wheel have the same rotation speed, why all two parts are connected to each other with cogwheels and rods to maintain synchronization.

摘要： In a hydrostatic device using an axial piston pump, a yoke is mounted so that it contacts the movable swash plate of the hydrostatic transmission. The yoke is biased by a spring-type mechanism to force the swash plate to return to neutral, and the set position of the yoke plate may be externally adjusted. A bias or load arm rotatably fixed to a housing at one end and connected to a spring at the other end is engaged to the yoke to provide the return force to the yoke plate. The yoke plate may have two legs to provide a return to neutral force to the swash plate in either direction, or one leg to provide the return to neutral force in only a single direction.

摘要： A transaxle includes an expansion bladder disposed in a sump for a hydraulic transmission, where the expansion bladder forms an air chamber separate from the sump and open to atmospheric pressure. The expansion bladder includes a set of ribs formed on an internal surface of a wall structure and extending into the air chamber to prevent unwanted collapse of the expansion chamber and improve its ability to collapse in a controlled manner as oil in the sump expands.

摘要： A hydraulic drive device having a pump and motor is disclosed, where the pump swash plate includes a pair of structural ribs and the housing has a pair of thrust ribs on an inner surface. Only one thrust rib is in contact with one of the structural ribs at a time, to permit arcuate rotation of the swash plate while limiting axial movement of the swash plate. The axes of rotation of the swash plate trunnion, input shaft and output shaft are in a common plane. A rotary bypass shaft for engaging transmission check plugs includes an external bypass arm. A pair of detents are externally formed on the housing, and the bypass arm includes separate pairs of openings to engage the pair of detents when the bypass arm is in different positions.

摘要： A reciprocator restraint assembly for a Z-crank axial piston machine is described. The assembly includes two gimbal arms each linked together at gimbal link joint that intersect at a point T. Point T lying in a medial plane M being defined as the plane passing through the point of coincidence of the crank and crankshaft axes to which the line that bisects the crank angle is normal. Each of the gimbal arms is pivotally mounted at an identical distance L from point T. A cylinder gimbal is pivotally mounted from the cylinder cluster and a reciprocator gimbal is pivotally mounted from the reciprocator. The reciprocator gimbal pivot axis is equidistant from point X and T as is the cylinder gimbal pivot axis. The orientations of the pivot axes of the two gimbal arms being mutual reflections in the medial plane M resulting in the point T lying on the medial plane M as the crankshaft rotates with respect to the cylinder cluster, and thus ensuring homo-kinetic rotational restraint between the reciprocator and the cylinder cluster.
摘要翻译：描述了一种用于Z型曲轴轴向活塞机的往复式约束组件。该组件包括两个万向臂，每个臂在万向节连接处连接在一起，在点T相交。位于中间平面M中的点T被定义为通过曲轴和曲轴轴线的重合点的平面，平分曲柄角度正常。万向架臂中的每一个以与点T相同的距离L可枢转地安装。气缸万向节从气缸组枢转地安装，并且往复运动万向节从往复运动器枢转地安装。往复运动万向枢转轴线与点X和T等距，与气缸万向枢转轴线一样。两个万向臂的枢转轴线的取向是中间平面M中的相互反射，导致当曲轴相对于气缸组旋转时，点T位于中间平面M上，并且因此确保了两个平衡臂之间的均匀旋转限制往复运动器和气缸组。

摘要： The invention relates to an axial piston machine of a kind that has a plurality of pistons each reciprocating in a respective cylinder in a direction substantially parallel or at an angle less than 30 degrees to a crankshaft axis. The crankshaft axis presents a crank that is at an angle to the crankshaft axis and to which a reciprocator is mounted. The reciprocator effects the controlled movement of the pistons in their cylinders via a connection mechanism that connects each said piston with said reciprocator. The machine includes at least one pair of rotational constraint mechanisms to constrain the movement between the reciprocator and the pistons.
