Operating shock absorber in compressor

Abstract

Abstract PURPOSE:To aim at relieving an operating shock, by paralyzing a compression function in a way of making discharge gas flow back to a low pressure chamber from a high pressure chamber in time of starting, while operating a control valve slowly after starting, limiting the flow of reflux gas to some extent, and restoring the paralyzed compression function to the original state by degrees. CONSTITUTION:When a solenoid valve 58 is opened and a scroll compressor is started, capacity of a compression space (c) formed by two volute parts 105b and 107b gradually decreases in proportion as this compression space (c) goes to the central part, and gas is discharged to a discharge chamber 109 from a discharge passage 110, but this gas is all made to flow back to a suction chamber 108 from a bypass passage 51 so that the compressor operates as much as zero percent. On the other hand, since the solenoid valve 58 is closed simultaneously with starting, a pressure discharge pipe line 59 interconnecting a back pressure chamber 56 to the suction chamber 108 is intercepted. Accordingly, motion of a control valve 53 toward a direction of closing a bypass passage 51 by dynamic pressure of reflux gas flowing into the passage 51 comes sluggish and gradually shifted to the closing direction so that a shock due to compressor operation is relievable.
