US Patent:

20110120176, May 26, 2011

Filed:

Nov 23, 2009

Appl. No.:

12/623897

Inventors:

Steven Craig Soliz - Dearborn Heights MI, US
Christopher Carleton Bartholomew - Dearborn Heights MI, US

Assignee:

DENSO INTERNATIONAL AMERICA, INC. - Southfield MI

International Classification:

F25B 43/02

US Classification:

62470, 417437

Abstract:

A compressor shaft may have a fluid inlet that leads into and may be concentric with a fluid inlet tube, which may be perpendicular to a longitudinal hole in the length of the shaft. An intermediate inlet into the longitudinal hole is located between the fluid inlet and an outlet at an end of the longitudinal hole. A drive plate mounted to the compressor shaft may have a protruding drive arm, which may use a holding mechanism (e.g. a pin) to connect to a swash plate. At certain swash plate angles, the intermediate inlet may be covered and sealed by the swash plate, or uncovered. The drive arm may define an internal bore and a through slot. At opposite ends, the bore may merge into the longitudinal hole and open into the through slot. The holding mechanism and/or swash plate guide may cover the bore in the slot and create a seal.
