    摘要： The invention relates to a radial piston hydraulic motor (100) and to a method in the control of a radial piston hydraulic motor. The radial piston hydraulic motor (100) includes a free rotation valve (50) which is built inside it and includes a spindle (19). The spindle (19) is disposed in a spindle cavity (20) and it is movable in the spindle cavity (20) such that, in a free rotation situation, shoulders of the spindle (19) block the inlet and outlet passages of working pressure. In a free rotation situation, springs (U1, U2 . . . ) press pistons (13a1, 13a2 . . . ) and press rollers (14a1, 14a2 . . . ) associated therewith to a bottom position and out of contact with a cam ring (11).

    摘要： A thermohydraulic engine comprising a power output member coupled to at least one compartment of variable volume. The compartment is placed in fluid communication with at least one of two or more expansion chambers. A liquid such as water fills the compartment and a fluid path to the at least one expansion chamber and partially fills said one expansion chamber. Means provided in each expansion chamber for introducing a product capable of producing energy by its expansion, whereby when the liquid in said one, partially filled expansion chamber has reached a predetermined level as a result of a liquid flow from the compartment, the product is introduced into the unfilled portion of said one expansion chamber and as a result of its expansion urges liquid back into the compartment to produce relative rotation between the compartment and the power output member. The cycle is repeated in the next expansion chamber and so on. The number of compartments is always less than twice the number of expansion chambers.

    摘要： A piston pump and a piston motor are provided. The piston pump includes a cylinder body, a piston, a main shaft, an end cover, and an oil dispensing mechanism. The oil dispensing mechanism includes an oil suction mechanism and an oil discharging mechanism. A roller is mounted on the piston, and the roller is rotatablely connected to the piston. A driving wheel is arranged on the main shaft, and the driving wheel is mounted in cooperation with the main shaft or is integrally formed with the main shaft. A driving groove is formed on the driving wheel, and a roller-path surface of the driving groove is a curved surface. The size of the driving groove is adapted to the size of an outer circle of the roller. The main shaft rotates to drive the driving wheel to rotate to further drive the piston to move along the cylinder bore.
