After ``A sectional view shown...'' in page 30, line 19 of the specification, there is a statement that says ``, Figures 16 to 18 show a conventional example, and Figure 16a is a perspective view showing a sub-seal member. , FIG. 16b is a perspective view showing an elastic seal member, FIG. 16c is a perspective view showing a seal member formed by assembling a sub-seal member and an elastic seal member, and FIG. 17 is a perspective view showing a part of the seal member. FIG. 1 is a sectional view showing a state where the control member is fitted into the U-shaped fitting groove;
Figure 8 is a sectional view taken along the line - in Figure 17.

Claims

[Scope of utility model registration request]

a casing block having on one side an annular recess formed by an outer circumferential wall surface, an inner circumferential wall surface, and an inner wall surface; An annular shape having a pressure receiving part on one side that can slide in the recess, and fitted in the annular recess so as to be rotatable in forward and reverse directions due to the differential pressure between the first pressure working chamber and the second pressure working chamber. a first annular seal portion that seals between an inner circumferential surface of the rotary piston and an inner circumferential wall surface of the annular recess, and an outer circumference of the rotary piston; a second seal part having an arcuate shape concentric with the first seal part sealing between the surface and the outer circumferential wall surface of the annular recess; and a second seal part rising substantially perpendicularly from one end of the second seal part and the first seal part, respectively. an outer circumferential wall surface of the annular recess, which is formed into a U-shape by a vertical portion and a horizontal portion connecting the two vertical portions;
A third seal portion that seals between an inner peripheral wall surface and an inner wall surface and a peripheral edge portion of the pressure receiving portion is integrally provided so as to connect between the first seal portion and the other end of the second seal portion. and sealing between one side of the rotary piston and the inner wall surface of the annular recess.
1. A rotary piston mechanism comprising: a seal portion; and a rotary piston mechanism, characterized in that flexible lips are provided on both side edges of at least the third seal portion of the seal member.
