    The present invention configured as described above operates as follows.
    That is, in Figs. 2-A to H, the sequential operations of the discharge valve 2 and the suction valve 3 when the piston 1 is sequentially raised and lowered are shown.
    In FIG. 2A, the piston 1 is rising and the suction fluid pushes up the suction valve 3 and the discharge valve 2 to maintain airtightness, while simultaneously raising the piston 1 and discharging the fluid on the cylinder. It is discharged out of the discharge port B through the valve 2.
    In FIG. 2-B, the piston 1 is raised so that the discharge valve 2 and the suction valve 3 come into contact with the upper end of the cylinder 5. At this time, the flow of the fluid is the same as in FIG.
    In FIG. 2C, the discharge valve 2 and the intake valve 3 are pushed to the upper surface of the cylinder 5 and lowered to the upper surface of the piston 1 as the piston 1 rises. At this point, the suction fluid acts to lower the suction valve 3 downward.
    In FIG. 2D, the piston 1 is stopped, but the suction valve 3 is completely lowered by the suction fluid to maintain airtightness, and the discharge valve 2 is also lowered by the action of the suction fluid to maintain airtightness. do. In this case, the suction fluid passing through the suction valve 3 and the discharge valve lowers the piston 1, and the fluid under the cylinder 5 is discharged out through the discharge valve 2 and the discharge port B. FIG.
    2E-H degree are sequential operation | movement when the piston 1 descends.
    In FIG. 2E, the suction fluid continuously lowers the piston 1, and the suction fluid presses the suction valve 3 and the discharge valve 2.
    In Fig. 2-F, the piston 1 is lowered so that the intake valve 3 and the discharge valve 2 are in contact with the cylinder 5.
    2G shows that the inlet valve 3 is pushed upward of the piston 1 by the inlet valve 3 being pushed by the inner wall of the cylinder 5 as the piston 1 is lowered.
    In FIG. 2H, the suction valve 3 and the discharge valve 2 are pushed up to the upper surface of the piston by the pressure of the suction fluid to maintain airtightness, and at the same time raise the piston 1.
    The ascending and descending operations in FIGS. 2A to H are the devices which repeat the same operation as long as the fluid is continuously introduced from the inlet port A and continuously discharged from the outlet port B.
    In FIG. 1B, the intake valve 3 'is the same as in FIG. 1A, but the discharge valve 2' serves to control the connection passage between the upper and lower portions of the piston 1 'of the cylinder 5'. . The outlet B 'is at the bottom of the piston 1' of the cylinder 5 'and is equipped with a spring 6 for raising the piston 1'.
    3A to D are the same as the operation of the intake valve 3 in the operation of FIG. 2A to the D, but the discharge valve 2 'is the piston 1' of the cylinder 5 '. The upper and lower portions of the c) are blocked to prevent the fluid on the upper portion of the piston 1 'from leaking to the lower portion of the piston 1'. At this time, the fluid of the lower part of the piston 1 'exits to the outlet B' of the cylinder 5 '.
    In Figs. 3-E to H, the piston 1 'is raised by the action of the spring 6 so that the suction fluid is in close contact with the piston 1' so that the suction fluid does not leak out of the piston. do.
    In FIG. 3H, the discharge valve 2 'is in close contact with the piston 1' at the pressure of the suction fluid, and prevents the fluid of the cylinder 5 'at the upper portion of the piston 1' from escaping by the suction fluid. Let the piston 1 'lower again. Therefore, in the present invention, the inlet valve (3) (3 ') and the discharge valve (2) (2') is mounted on the reciprocating piston (1) (1 ') and the cylinder body directly according to the reciprocating motion of the piston (1) (5) (5 ') is in contact with the intake and discharge valve (3) (3') (2) (2 ') so that the direction change is simple and the failure is less and the operation time is shorter than the indirect type. It is a device that can reciprocate quickly.
