US Patent:

47947659, Jan 3, 1989

Filed:

Mar 27, 1987

Appl. No.:

7/031022

Inventors:

Thomas J. Carella - Niagara Falls NY
John N. Bannan - Lockport NY

International Classification:

F25B 4300

US Classification:

62512

Abstract:

An evaporator assembly includes a housing having a fluid inlet and a fluid outlet. A heat exchange core is in direct fluid communication with the fluid inlet for interchanging heat between refrigerant and air flow over the core. An accumulator chamber is contained within the housing and is in direct fluid communication between the heat exchange core and the fluid outlet for collecting and separating vaporized and unvaporized refrigerant directly from the heat exchange core and for providing an environment of vaporized refrigerant about said fluid outlet.

International Classification:

US Classification:

417222S

Abstract:

A variable displacement compressor having a rotary drive shaft coupled to a gas pressure positioned wobble plate carried by a drive mechanism including a drive journal and journal sleeve on the rotary drive shaft and a drive lug connected to the drive shaft having a slot operatively connected by a coupling pin to the journal. Thrust bearings located in the cylinder head and front head of the compressor axially position the drive mechanism within a gas pressured crankcase. The rear thrust bearing includes a race engaged by a coil spring on the shaft to provide relative axial movement between the shaft and the rear thrust bearing to compensate for end play between the thrust shoulders and the thrust bearings following assembly of the cylinder head and front head. The coil spring has a first predetermined biasing force when the wobble plate is in a full stroke position to maintain a minimum spring load on the thrust bearings to reduce wear during operation of the compressor at high air conditioning loads and the coil spring is shifted into a compressed position to provide an increased load on the thrust bearings in a direction to resist load reversals on the shaft when the compressor is operating under low air conditioning load conditions.
