摘要:
A swash plate type compressor having axially spaced inlet chambers and outlet chambers located on the side of angularly spaced pistons having each side thereof pump chambers which are connected to inlet chamber when the medium is introduced into the pump chambers, and are connected to the outlet chamber when the medium is removed to the outlet chambers. A swash plate chamber is arranged inside the cylinder block and cooperates with the pistons via respective shoes for reciprocating the pistons in the respective cylinder bores. An inlet of the fluid to be compressed is opened to the swash plate chamber at a circumferential position along the inner wall of the swash plate chamber. Communication passageways for connection of the swash plate chamber with the inlet chambers are arranged on position spaced farthest from the inlet port. The flow of the lubrication oil contained in the gas to be compressed is generated inside the swash plate chamber and comes into contact with all of the shoes, to lubricate same, before being introduced into the communication passageway from the swash plate chamber.

A swash plate type compressor having a compressor casing accommodating a swash plate operated compressing mechanism compressing a refrigerant gas supplied from a suction side of a refrigerant circulating circuit and discharging a compressed refrigerant gas into a discharge side of the circuit, and an internal lubricating system for lubricating movable elements of the swash plate operated compressing mechanism by using a lubricating oil reserved in a swash plate chamber and an oil sump provided in the bottom of the compressor casing, the compressor casing having a refrigerant and lubricant separating chamber for separating a lubricant component from a lubricant suspended refrigerant gas generated in the swash plate chamber by a high pressure blow-by refrigerant gas and a mist of the lubricant oil when the gas flows from the swash plate chamber toward the suction side of the refrigerant gas circulating circuit, and a refrigerant gas evacuation passageway extended from the refrigerant and lubricant separating chamber to the suction side of the refrigerant circulating circuit to permit an evacuation of the refrigerant gas after the lubricant separation.

A continuous seal ring member fitted in a ring groove of a piston of a compressor. The seal ring member has a washer-like initial shape with an internal diameter smaller than an outer diameter of the piston, whereby the inner peripheral portion of the seal ring member is expanded when the seal ring member is fitted in the ring groove. The outer peripheral portion of the ring seal member is then axially and inwardly collapsed relative to the inner peripheral portion thereof so that one of the side surfaces of the initial seal ring member constitutes an outer sealing surface for engagement with the cylinder bore and the outer peripheral portion in the original shape is arranged on the side of said compression chamber. A backup ring member fitted in the ring groove on the side of the continuous seal ring member remote from the compression chamber has a surface area abutting against the side surface of the ring groove on the side remote from the compression chamber and sufficient to retain the continuous seal ring member in the ring groove.

A thrust bearing lubricating system of a swash plate type compressor having a main lubricating oil passageway bored in the center of a drive shaft on which a swash plate is mounted to be axially supported by a pair of front and rear thrust bearings, an oil pumping mechanism for pumping lubricating oil from an oil sump in the bottom of a cylinder block assembly and supplying the lubricating oil into the main lubricating oil passageway, and at least front and rear radial branch lubricating oil passageways formed in the drive shaft to be communicated with the main lubricating oil passageway and to allow spouting of the lubricating oil toward the front and rear thrust bearings, the front and rear radial branch lubricating oil passageways having different cross-sectional areas from one another to equalize an amount of lubricating oil supplied to both thrust bearings.

A first reproduced color under signal is delayed by one or two horizontal periods by a delay circuit, and this delayed second reproduced color under signal and the aforementioned first reproduced color under signal have their frequencies converted individually by first and second frequency converters into standard color signals. An oscillatory frequency signals of 2n of carriers for the aforementioned frequency conversions are divided to have the aforementioned carrier frequencies and to produce four carriers having phases of 0, 90, 180 and 270 degrees. These carriers are selectively fed to the first and second frequency converters by switches so that the two frequency-converted signals are subtracted or added in phase or in opposite phase to clear the noise (or crosstalk component), which is caused by the crosstalk between the tracks.
摘要:
A multi-piston swash plate type compressor for an air-conditioning system used in a vehicle such as an automobile, including a cylinder block body having a swash plate chamber formed therein for receiving a swash plate and cylinder bores formed therein for receiving pistons which are reciprocated by rotation of the swash plate. The compressor has a suction chamber which is fed with a refrigerant including lubricating oil from an evaporator of the air-conditioning system and a discharge chamber which feeds the compressed refrigerant to a condenser of the air-conditioning system. When the compressed refrigerant is discharged from the cylinder bore into the discharge chamber through a discharge reed valve, all of the discharged refrigerant is impinged on the peripheral and inner wall so as to separate the lubricating oil from the refrigerant, whereby an effective damping and sealing oil layer is formed between the discharge reed valve and the valve seat thereof.
