    Abstract: A compressor may include a crankshaft, first and second cylinder housings, first and second rotors, a divider plate, and first and second valves. The crankshaft includes first and second eccentric portions. The cylinder housings define cylindrical recesses. The rotors are disposed within respective cylindrical recesses and engage respective eccentric portions of the crankshaft. The first rotor and the first cylindrical recess define a first compression chamber therebetween. The second rotor and the second cylindrical recess define a second compression chamber therebetween. The divider plate may be disposed between the cylinder housings and may include first and second fluid openings in communication with the first and second compression chambers. The valves may be moveable relative to the divider plate between a first position allowing fluid flow through the fluid openings and a second position restricting fluid flow through the fluid openings.

    Abstract: A system and method for controlling the volume ratio of a compressor is provided. The system can use a port (88) or ports in a rotor cylinder to bypass vapor from the compression chamber to the discharge passage of the compressor. A control valve (90) can be used to open or close the port or ports to obtain different volume ratios in the compressor. The control valve (90) can be moved or adjusted by one or more valves that control a flow of fluid to the valve. A control algorithm can be used to control the one or more valves to move the control valve to obtain different volume ratios from the compressor. The control algorithm can control the one or more valves in response to operating parameters associated with the compressor.

    Abstract: A compressor (20) has an unloading slide valve (100). The valve has a valve element (102) having a range between a first condition and a second condition, the second condition being unloaded relative to the first condition. A piston (124) is in a cylinder (128) and mechanically coupled to the valve element. A control valve (40; 42) is coupled to a headspace (138) of the cylinder to selectively expose the headspace to a fluid source (144), pressure of fluid in the headspace producing a force on the piston and valve element in a direction from the second condition toward the first condition. The compressor includes means (190, 192; 210; 220) for relieving excess pressure in the headspace.

    Abstract: The invention provides a method of operating a screw compressor equipment without reducing the efficiency, in which a screw compressor 1 of which the internal volume ratio is variable by means of an internal volume ratio control valve is driven by a driving machine 2, the discharge side of the compressor 1 is communicated with the suction side of the same by way of a bypass control valve 9 as needed, the internal volume ratio control valve 3 is always controlled to be located at a position calculated so that the internal volume ratio with which the polytropic efficiency is maximum is obtained, and gas flow rate is controlled by controlling the rotation speed under normal conditions and controlled by controlling the bypassing flow rate from the discharge side to the suction side under very low rotation speed.
