モータその他の駆動源を示す。 In the illustrated example, the cylinder liner 2 has a concave surface 2a on the upper surface, and a convex surface 2a on the lower surface of the cylinder head 4.
b, and both 2 and 4 are fitted into each other by the concave surface 2a and the convex surface 2b, and an O-ring 12 is provided on the outer periphery of the O-ring 12, and the screws 13 on the outside are used to tighten and connect them to each other. At this time, the valve plate 7 and the seat plate 9 are vertically overlapped and fitted in advance in the concave surface 2a, and the concave portion 10 is previously formed on the outer periphery of the concave surface 2a. It was arranged to engage with the convex portion 11 formed in advance on the periphery. The reed valve 6 is bent into the transparent window 8 on the lower side and opens into the valve hole 1 on the upper side.
The seat plate 9 is designed to have a thickness corresponding to the lift amount of the reed valve 6. In the drawings, reference numeral 15 indicates a motor or other drive source connected to the piston 3 described above.

向上できる等の効果を有する。 In this way, according to the present invention, the intake valve 5 is superimposed on the thin annular upper valve plate 7 integrally provided with the reed valve 6 for opening and closing the valve hole 14 provided with the cylinder head 4, and the lower surface of the valve plate 7. It consists of a transparent window 8 through which the reed valve 6 to be lifted faces, and a lower seat plate 9 having a support piece 16 for supporting the curved base of the reed valve 6 to be lifted. 9 is sandwiched between the opposing surfaces of the cylinder liner 2 and the cylinder head, making the assembly of the intake valve 5 simple and easy, and the reed valve 6 on the thin annular valve plate 7 is responsive. Moreover, the bending stress applied to the curved base of the reed valve 6 during response is supported by the support piece 16 on the seat plate 9 and is not concentrated on the curved base of the reed valve 6, thereby improving durability. It has effects such as improving sexual performance.
