摘要： There is provided an idling engine speed control apparatus which can economically and suitably control an idling engine speed in the case where a variable displacement type compressor (1) with a variable displacement is mounted as a part of an automotive air conditioning system. At the time of idling, a duty ratio of a control valve current value sent as an external signal (S) to a control valve (16) is sent also to an engine controller, and the engine control apparatus controls the output of an engine on the basis of the duty ratio. For example, when the duty ratio becomes high from a small value, since the present operating state of the compressor (1) is in the direction where the differential pressure becomes high and the displacement is increased, it is expected that a large load is applied to the engine. Thus, in this case, the engine output is controlled correspondingly to a large duty ratio and the idling engine speed is made high.

摘要： Provided is an operation control method for a BOG multistage displacement compressor including connected multiple displacement compression units (9,10) for compressing boil off gas (BOG) generated from liquefied natural gas, including: under a predetermined state, performing operation control so that the ratio (load ratio) of a load of a low-pressure stage compression unit (9) to a load of a high-pressure stage compression unit (10) in the BOG multistage displacement compressor is larger than load ratios under states other than the predetermined state. Namely, the BOG multistage displacement compressor is configured so that suction temperature in the low-pressure stage compression unit (9) can be detected, and the predetermined state is set to a state where the detected temperature of the suction temperature is equal to or higher than a set temperature that is preset. According to such a method, even if the low-pressure stage side suction gas has a temperature higher than that in steady operation, the load (gas load) due to a differential pressure between suction gas and discharge gas on the high-pressure stage side can be prevented from exceeding an allowable gas load.

摘要： The invention relates to a vacuum pump, in particular, a Roots type pump, comprising a lobe (12) arranged in a suction chamber (10). The pressure side (30) of the pump is connected to the suction side (20) by means of a connecting channel (22). A valve (24) is arranged in the connecting channel (22), which closes a through opening (32). On exceeding a set pressure difference between the pressure side (30) and the suction side (20) the valve opens automatically. In order to reduce the necessary space and to reduce the switching noise from the valve the valve body is embodied as a flap valve (28).
