Claims

[Scope of utility model registration request]

A first piston that slides into the large diameter cylinder and a first piston that slides inside each of the small diameter cylinders that are located on both sides of the first piston are arranged in a housing in which small diameter cylinders are provided concentrically on both sides of the large diameter cylinder. two second pistons that are movably slidably fitted;
and the first piston are connected so as to be displaceable in the radial direction by a connecting member, and high pressure fluid supply ports are provided in the large diameter cylinder located on both sides of the first piston, and high pressure fluid supply ports are provided from the high pressure fluid supply ports. In the pressure transducer, the first piston is caused to reciprocate by alternately supplying high pressure fluid into the large diameter cylinder, and the pressure of the fluid supplied into the small diameter cylinder is increased by the second piston. Each of the second pistons is rotatably fitted into the cylinder, and the high-pressure fluid supply port is connected to the high-pressure fluid supply port so that the axis of the high-pressure fluid supply port is located slightly inside the circumferential tangent of the second piston. A predetermined number of grooves are provided in the circumferential surface of each second piston in the axial direction, and the grooves have a length that always faces the high-pressure fluid supply port within the stroke range of the piston, so that the high-pressure fluid is supplied with the high-pressure fluid. A pressure transducer characterized in that the pressure transducer is configured to apply rotational force to each of the second pistons.
