摘要： PROBLEM TO BE SOLVED: To enable highly efficient operation using low viscous fluid such as water in a vane type rotary machine having a rotor provided with vanes, by arranging rotor slit members made of a low friction/abrasion material and formed with rotor slits for housing the vanes. SOLUTION: A rotor 15 rotatably housed in a cylindrical cam casing 10 has spirally inserted vanes 60 brought into contact with the inner surface of the cam casing. By rotating a main shaft attached to the rotor 15, operation fluid suctioned from a supply port 11 to a portion between the adjacent vanes 60 is sequentially compressed, and discharged from a discharge port 13. In such a case, a rotor slit member 70 made of a low friction/abrasion material is attached to the rotor 15. The vanes 60 is reciprocatably housed in rotor slits 71 formed on the rotor slit members 70. It is thus possible to reduce frictional resistance caused by sliding between the vanes 60 and the rotor slit members 70 to attain highly efficient operation.

摘要： PROBLEM TO BE SOLVED: To provide a hydraulic actuator requiring no separate provision of a water jet device used for purifying work in the work environment by providing a hydraulic actuator with a nozzle, and a flow passage supplying high pressure water to a nozzle in the inside of the hydraulic actuator. SOLUTION: A hydraulic motor 10 is provided with a casing 11 in which a return port 17 to be connected to a tank as well as a port supplying high pressure water are provided. A flow passage communicating with a supply port 16 is divided into two, where one of the flow passages communicates with a drive side to convert a movement of a piston inside of the casing 11 to a rotational movement and the other communicates with a nozzle 19 provided at the casing 11. With the integral constitution of the motor and the nozzle 19, work carried out by driving the motor 10 and washing work carried out by jetting water are implemented simultaneously. It is also made unnecessary to provide piping parts or hose, etc., for performing connection between the motor 10, nozzle 19 and a high pressure water generation device.
