    Abstract: PURPOSE: To improve economic efficiency by reducing the number of constituting part items in a package type screw compressor. CONSTITUTION: This screw compressor has two-stage compressors of a low pressure stage compressor 2 and a high pressure stage compressor 3. Motive power is transmitted to the compressors of these respective stages via a speed increaser 5 from an electric motor 4. Delivery gas becoming a high temperature by being compressed by the low pressure stage compressor is cooled by an intercooler 33. Delivery gas becoming a high temperature by being compressed by the high pressure stage compressor is cooled by an aftercooler 34. A casing of the intercooler 3 and the aftercooler 34 is integrated with a speed increaser casing 5 to reduce the number of part items. A cooler part composed of the intercooler and the aftercooler and a speed increaser casing part are separately arranged to reduce influence exerted on the speed increaser casing by heat of compressed air.

    Abstract: The multicylinder rotary compressor has a number of cylinders housing rolling pistons which are rotated inside the cylinders by a common crankshaft. Each cylinder has a separate suction pipe. At least one of the suction pipes has a check valve which may be closed to unload the cylinder to which the suction pipe is connected. The check valve has a housing and a slider. The check valve may be closed by introduction of high-pressure refrigerant gas into the space beneath the slider to push it to the closed position when a cylinder is to be unloaded. Alternatively, the check valve is closed by a spring made of a shape-memory alloy and a heater for heating the spring above a prescribed temperature at which the alloy changes shape.
