A compressor includes orbiting and non-orbiting scrolls forming first and second fluid pockets therebetween. First and second ports are disposed in the non-orbiting scroll and radially spaced apart from each other. The first port communicates with the first pocket at a first radial position and the second port communicates with the second pocket at a second radial position. A blocking device is movable between a first position preventing communication between the ports and a fluid source and a second position allowing communication between the ports and the fluid source. The first and second pockets have first and second pressures, respectively. One of the pressures may have a disproportionate pressure change compared to the other of the pressures after at least one of the pockets communicates with the fluid source through at least one of the ports. The disproportionate pressure change biases the orbiting scroll relative to the non-orbiting scroll.

The present invention also provides a screw compressor in which an oil path is provided in the screw bore outer circumferential portion of the casing body to prevent contact between the screw rotor and the screw bore portion of the casing body. The present invention also provides a screw compressor which includes a heat sink to increase the heat transfer area for exchanging heat between the oil and refrigerant gas or liquid refrigerant, thereby achieving increased resistance to returned liquid refrigerant.
194 Suction oil injection for rotary compressor US10097877 2002-03-14 US07011183B2 2006-03-14 Jean-Louis Picouet
An apparatus and system for immediately lubricating a compressor within a compressor system using a suction oil line apparatus. The compressor system comprises a compressor, a power source for operating the compressor, a tank capable of storing oil therein, a conventional oil line, and a suction oil line apparatus. The suction oil line apparatus can comprise a suction oil line and a valve. When the power source is actuated, gas is introduced into a suction cavity within the compressor, drawn into a compression chamber within the compressor, and compressed. The compressed gas is discharged into a tank thereby elevating a tank pressure. The elevated tank pressure causes the oil within the tank to be transported through the suction oil line. Transportation of the oil through the suction oil line permits immediate lubrication of the compressor to occur following start-up of the compressor, immediate being from about one second to about one minute. Start-up can comprise initiation of the compressor, movement of components within the compressor, movement of intimate components within the compressor, or actuation of the power source. When the tank pressure reaches a pre-determined pressure, the valve in the suction oil line is closed. The closed valve results in the oil being prohibited from flowing through the suction oil line and permitted to flow through the conventional oil line. As such, the compressor remains continuously lubricated. Further, immediate lubrication can be accomplished without the need for a back-pressure valve or pump.

A compressor and oil separator assembly for compressing a fluid includes a suction end, a discharge end, and first and second rotors rotatably mounted between the suction and discharge ends. A discharge line communicates with the discharge end, and an oil separator communicates with the discharge line. An oil sump communicates with the oil separator and an oil supply line communicates between the oil sump and the rotors. A bleed line selectively communicates between the discharge line and the oil supply line for equalizing a pressure differential between the suction end and the discharge end without causing substantial backward rotation of the rotors or displacement of oil to the rotors through the oil supply line. Preferably, the assembly further includes a valve that defines a portion of the discharge line and is also coupled to the bleed line.
