Appl. No.:

12/362587

Inventors:

Nikolaos Adonis Adonakis - West Bloomfield MI, US

Assignee:

Axletech International IP Holdings, LLC. - Troy MI

International Classification:

F16D 57/00

US Classification:

267 6427, 267221, 267226

Abstract:

A strut assembly includes a damper having a housing and a rod moveable relative to the housing along a longitudinal axis. The strut assembly includes a flexible membrane configured to receive a pressurized gas to form an air spring. A coil spring defines an inner diameter with the housing disposed within the inner diameter to permit relative movement between the coil spring and the housing. The coil spring is at least partially disposed outside the flexible membrane relative to the longitudinal axis.

Filed:

Oct 21, 1991

Appl. No.:

7/779761

Inventors:

Robert L. Swadner - East Amherst NY
Nikolaos A. Adonakis - Grand Island NY

Assignee:

General Motors Corporation - Detroit MI

International Classification:

B60H 132

US Classification:

62244

Abstract:

A primary air conditioning system for a vehicle has an engine driven compressor which supplies refrigerant to a cooling subsystem comprising a condenser, and expansion valve, and an evaporator. A precooling system has an absorption type system which supplies refrigerant to the cooling subsystem which it shares with the primary system. A combustion unit fueled by the vehicle fuel supplies heat to the generator of the precooling system. The precooling system is used to at least partially cool the vehicle interior before it is occupied, and the primary system is used when the engine is running.

Appl. No.:

8/398335

Inventors:

Michael J. Burkett - Lockport NY
Nikolaos A. Adonakis - Grand Island NY

Assignee:

General Motors Corporation - Detroit MI

International Classification:

F01B 300

US Classification:

92 71

Abstract:

A swash plate driven piston compressor includes means to maintain the pistons on their respective cylinder bore axes. A resilient alignment ring bears on the radial inner sides of the pistons at a point near the back ends of the pistons. The ring moves passively with the swash plate, without affecting its operation. The ring prevents the pistons from tipping radially inwardly and off their axes as they retract. The piston design is not appreciably changed, and the ring fits within otherwise empty space within the compressor housing.

Assignee:

General Motors Corporation - Detroit MI

International Classification:

F04B 5312

US Classification:

417550

Abstract:

A swash plate compressor with single ended pistons improves piston stability by providing the ends of the pistons with open, conical rims, the outer surfaces of the which match, and thereby enlarge, the outer surface area of the pistons. The pistons therefore have increased sliding support within the cylinder bores, but without significant added mass. The pistons work in cooperation with matching conical protrusions on the discharge valve plate, which substantially fill the interior of the rims at piston full stroke. The piston compression ratio is therefore kept substantially the same.

Assignee:

General Motors Corporation - Detroit MI

International Classification:

F16J 100

US Classification:

92177

Abstract:

An automotive air conditioning compressor of more compact and efficient design is achieved with a unique cylinder bore and piston shape. While the cylinder bores and pistons are arrayed in a circle about the central axis of the round cylinder block, the bores and pistons themselves are not round in cross section. Instead, each has a pair of flattened sides lying more or less parallel to radial planes of the cylinder block. As a consequence, only solid webs separate the cylinder bores, not empty spaces, as in a conventional block. The ratio of total bore volume to block volume is greater, and the compressor is more compact for a given capacity. In addition, the non round cross section of bores and pistons resists piston twisting.

Nikolaos A. Adonakis - Grand Island NY

Assignee:

General Motors Corporation - Detroit MI

International Classification:

F01N 100

US Classification:

181 05

Abstract:

An attenuator for pressure and sound energy pulsations, such as are commonly produced in refrigerant gas discharged from a piston-type refrigerant compressor, is provided. The attenuator includes an annular elastomeric body supported by a rigid tubular housing. The body forms a cavity filled with a damping fluid and annular dividers define multiple chambers that are concentrically disposed about a central refrigerant gas flow passage. Damping tracks are provided in the dividers to allow fluid flow between the chambers. As refrigerant gas flows through the passage, the pressure/sound pulsations are flattened and smoothed. The resilient walls of the body are designed to bulge inwardly for a maximum 50% restriction. Gas flow orifices of the dividers have substantially the same cross-sectional area as the refrigerant line.
