Abstract: PURPOSE:To reduce the load applied to a swing scroll at the time of restarting the compressing operation by disposing a release valve for reducing a differential pressure between the inlet port side and the back pressure chamber side on at least one of the both sides. CONSTITUTION:When a driving shaft 6 is rotated to rotate a swing scroll 8, the air is sucked from an inlet port 2A through an intake opening 4, compressed in a compression chamber 10 formed between a fixed scroll 3 and the swing scroll 8, and then discharged from a discharge opening 5. In this case, an exhaust port 21 communicated with a back pressure chamber 11 is formed on the major diameter cylinder part 1B of a casing. Also, an electromagnetic release valve 22 for releasing the compressed air in the back pressure chamber 11 to the outside is disposed on the exhaust port 21. The release valve 22 is opened only for a determined time at the time of restarting the compressing operation. Hence, the pressure in the back pressure chamber 11 is reduced to reduce the differential pressure with the compression chamber 10 side, whereby the load applied to the swing scroll 8 is reduced.

Abstract: PURPOSE:To reduce variation in current value with temperature, etc., by setting the gate-source voltage of the 2nd MOSTR to a voltage which is much lower than the gate-source voltage of the 1st MOSTR and close to a threshold voltage by a stabilized voltage source. CONSTITUTION:An N-type MOSTR 1 is a current output stage and its gate is connected directly to the gate of an N-type MOSTR 3. The stabilized voltage source 4 which supplies a voltage V1 is connected to the source of the TR 3 and its polarity is set in the same direction with the gate-source voltage of the TR 3 when viewed from a reference potential point (earth). Then, equations A and B hold, where ID1 and VGS2 are the grain current and gate- source voltage of the TR 1 and ID2 and VGS2 are the drain current and gate- source voltage of the TR 3 respectively. Further, an equation C holds when the ID2 is much lower than the ID1 and VGS1-VTH is therefore much higher than VGS2-VTH. Consequently, there is no variation in ID1.
