IPC: F04C18/02
Filed: 1986-12-16
Abstract: PURPOSE:To obtain the captioned device having high efficiency and the superior durability by realizing an oil feeding passage controller having a wide application range by utilizing the pressure difference between in a suction chamber and compression chamber which does not communicate to a discharge chamber and the suction chamber. CONSTITUTION:A compressor starts operation, and a swirl scroll 10 performs a turning movement to inhale the gas in a suction chamber 33 into a compression chamber, and said gas is compressed to a certain compression ratio and then discharged into a discharge chamber 5. Further, a differential pressure is generated between the back pressure chambers of an oil feeding passage control valve device 17e installed midway in an oil feeding passage, and an opening/closing valve is opened to communicate to the oil feeding passage, and the lubricating oil in the oil reservoir 18 of the discharge chamber 5 is supplied to a compression chamber B39. When no lubricating oil exists in the discharge chamber oil reservoir 18, a large quantity of the compressed gas having high pressure and high temperature flows into the compression chamber B39 through the oil feeding passage, and the differential pressure between the both back pressure chambers exceeds a set value, and the valve body is closed to close the oil feeding passage. When the compressor stops, the valve body is retreated by a piston spring 38, etc., aud the opening/closing valve is closed. Therefore, the inutile flow out of the lubricating oil in the discharge chamber oil reservoir 18 is prevented, and the effective use of the lubricating oil is permitted.

Title: Current limiting circuit
Inventor: HAYAKAWA JUNJI
IPC: H02H7/20
Filed: 1996-11-13
Abstract: PROBLEM TO BE SOLVED: To attain current limiting with high accuracy by making current flow through a signal line with the second transistor which forms a current mirror circuit with the first transistor to change a voltage level of a control signal. SOLUTION: This circuit is connected to a constant-voltage power supply circuit 40 through a terminal 30 connected to a resistor R. When load 1 is driven, high level gate voltage is supplied to the gates of an output transistor 2 and a current detecting transistor 3 through the resistor R and a signal line L from the constant voltage power supply circuit 40. Load current I1 runs through the load 1 via the output transistor 2 from the power supply voltage VD. The outputted voltage of an operational amplifier OP changes so that the output transistor 2 and the current detection transistor 3 may have the same electric potential each other, and current I2 corresponding to the load current I1 runs from the power supply voltage VD to the output terminal of the operational amplifier OP through the current detecting transistor 3 and the first transistor 4.  It is thus possible to conduct current limiting with high accuracy.
