Appl. No.:

13/428973

Inventors:

Justin K. Russell - Needville TX, US
Richard K. Hotze - Houston TX, US

Assignee:

Compressor Engineering Corporation - Houston TX

International Classification:

F16K 1/44
F04B 53/10
F16K 17/04

US Classification:

417559, 137542, 251333, 251368, 1375121

Abstract:

A miniature poppet valve assembly for a high-speed compressor, the miniature poppet valve assembly includes a plurality of miniature poppets, each characterized by a stem and a head with a maximum head diameter of no more than 0.9 inches; a cage having a plurality of counter bores disposed therein, each counter bore disposed for receipt of a poppet; and a seat plate overlying the cage, the seat plate including a plurality of through bores axially aligned with the counter bores of the cage. Each counter bore includes a chamfered edge against which the head of the poppet seats, thereby forming a seal. The chamfered edged is provided with a chamfer angle of approximately 30 degrees. In one embodiment, poppet heads have a convex head surface and are shaped so that the tangent angle at the point of contact between the edge and the head is approximately 30 degrees.
