    Abstract: A system includes a compressor with an orbiting scroll member having a first end plate and a first spiral wrap. A non-orbiting scroll member has a second end plate and a second spiral wrap, the second spiral wrap forming a meshing engagement with the first spiral wrap to create a plurality of compression chambers between a suction port and a discharge port. A first port in communication with a first of the plurality of compression chambers selectively injects an injection fluid into the first of the plurality of compression chambers to increase a compressor capacity and selectively leaks a first compressed fluid from the first of the plurality of compression chambers to reduce the compressor capacity. A second port in communication with a second of the plurality of compression chambers selectively leaks a second compressed fluid from the second of the plurality of compression chambers to reduce a compressor capacity.

    Abstract: A screw compressor includes a casing, a screw rotor, an oil sump containing lubricant oil, a lubrication passage and a flow rate controller. The screw rotor is inserted in a cylinder portion of the casing to form a fluid chamber. The screw rotor rotates to suck a fluid into the fluid chamber for compression. The lubrication passage supplies the lubricant oil in the oil sump to the fluid chamber due to a difference in pressure between the oil sump and the fluid chamber. The flow rate controller reduces a flow rate of the lubricant oil supplied to the fluid chamber in accordance with a decrease in operating capacity of the screw compressor.

    Abstract: A shunt pulsation trap for a rotary lobe blower (pump) or vacuum pump reduces pulsation, NVH and improves efficiency without increasing overall size of the blower or pump. Generally, a rotary lobe blower (pump) or vacuum pump with the shunt pulsation trap has a pair of interconnected and synchronized parallel multi-lobe rotors housed in a transfer chamber with the same number of lobes for propelling flow from a suction port to a discharge port of the transfer chamber without internal compression. The shunt pulsation trap comprises an inner casing as an integral part of the transfer chamber, and an outer casing oversized surrounding the inner casing, therein housed various pulsation dampening means or pulsation energy recovery means or pulsation containment means, at least one injection port (trap inlet) branching off from the transfer chamber into the pulsation trap chamber and at least one feedback port (trap outlet) communicating with the blower outlet pressure.
