Abstract
PURPOSE: To facilitate a capability of control over each of the operations of the compressor by a method wherein a check valve is arranged in a closed space formed at the end plate of the fixed scroll and at the same time an outlet of the check valve, a discharge port of the compressor and the inlet port thereof are connected through a three-way valve.
CONSTITUTION: Pressur guide pipe 18A and the connector pipe 17 are communicated to each other through three-way valve 20 and a return pipe 19A is shut off, thereby the compressor may be operated in the same manner as that of a conventional scroll type compressor under the action of the check valve 16A, 16b. The pipe 17 is communicated with the suction pipe 19 through thee-way valve 20 and the pipe 18A is shut off, thereby the fluid is discharge through the check valves 16A, 16B while the closed spaces 14A, 14B are communicated with the through-pass holes 15A, 15B during a rotation of the movable warp 9B and no increase of the hydraulic pressure is found in the spaces 14A, 14B so that an operation of low power may be performed. In this way, a control over a capability of the scroll type compressor may be performed and both high and low loading operations may be performed by one compresor machine.
