| A scroll machine has an intermediate pressure cavity which is operable to open and close a leakage path between the discharge zone and the suction zone of the scroll machine. The leakage path is closed when intermediate pressurized fluid is supplied to the cavity and the leakage path is open when the cavity is open to the suction zone of the compressor. A valve (102) which can be mechanical or electrical is used to open and close a passageway extending between the cavity and the suction zone of the machine. A high pressure relief valve is incorporated into the design of the compressor to prevent slugging. The high pressure relief valve will release the intermediate pressurized fluid to suction and/or discharge when the pressure within the intermediate pressure cavity exceeds a predetermined value. | ||||||

| 79 | Idling speed controller | JP6382899 | 1999-03-10 | JP2000257464A | 2000-09-19 | IJIRI MAKOTO |
| PROBLEM TO BE SOLVED: To control idling speed appropriately at a low cost, where a variable capacity compressor in which a discharge volume is changeable is incorporated as a part of an air-conditioning system in a vehicle. SOLUTION: During idling, the duty ratio of a control valve current transmitted to a control valve is also transmitted to an engine controller as an external signal S (step 106). The engine controller controls an engine output based on the duty ratio. When the duty ratio is charged from small to large, for instance, a differential pressure ΔP increases, and the discharge volume is in the tendency to increase in the present operation condition of a compressor. Therefore, a large load is expected to be applied to an engine. Consequently, in this case, the engine output is controlled in matching with the large duty ratio, and the idling speed is increased. | ||||||
