Filed:

Feb 20, 1987
Appl. No.:

7/018813
Inventors:

David A. Bramstedt - Sheboygan WI
Thomas R. Hetzel - Sheboygan WI
Charles E. LaBelle - Oostburg WI
Assignee:

Thomas Industries, Inc. - Louisville KY
International Classification:

F16J 908
F04B 3910
US Classification:

92240
Abstract:

A seal and retainer assembly for an air compressor piston includes a cup-shaped seal with its marginal edge extending at an angle relative to the cylinder wall, the seal having a notch extending circumferentially at the base of its marginal edge defining a hinge which allows pivoting of the marginal edge relative to the main body portion of the seal which is clamped to the piston. A head plate includes an air intake port for communicating the compression chamber with an air inlet and a discharge port for communicating the compression chamber with a compressed air discharge outlet, each of the ports having a flexible spring closure member cooperating with an inclined valve seat to allow the ports to be open whenever the compressor is shut off.
