IPC: F16J15/3276
Filed: 1986-05-09
Abstract: PURPOSE:To sufficiently maintain durability even for a high pressure and a high speed of an air clutch, by providing an annular tension part, which connects a point end lip part of an annular seal member with the other end part of a reinforcing member, and forming a plurality of communication holes, which connect a hollow chamber with a pressure air chamber, in the annular tension part. CONSTITUTION:In case of an engine in rotation, when a clutch is connected, air of an air supply source 30 is forced to be fed to a pressure air chamber 7 between seals S passing through a control mechanism 29 and a pipe 28. Subsequently, the air, which is supplied passing through a pipe 26 or the like to a pressure air chamber 20 in a cylinder part 16, forces a pressure plate 19 to come into contact with a clutch disc 12. When the clutch is placed in a connection condition, a pressure in the pressure air chamber 7 between the seals S is equalized to the pressure in a hollow chamber 5, and tightening force F is generated by a seal width W of a lip part 1a of a seal member 1. Simultaneously with the above, tensile force is generated in a tension part 40, consequently an increasing rate of the tightening force F decreases in accordance with an increase to the high pressure of the hollow chamber 5. Accordingly, a heat generation amount in the lip part is suppressed to a small value.
