    摘要： A compressor (20) is provided with compression mechanisms (61, 62) to have four compression chambers (61, 62, 63, 64) in total. In the compressor (20), the first compression chamber (61) and the second compression chamber (62) differ in the phase of capacity changing cycle from each other by 180° and the third compression chamber (63) and the fourth compression chamber (64) also differ in the phase of capacity changing cycle from each other by 180°. In a cylinder nonoperating mode, refrigerant is compressed in a single stage in each of the first compression chamber (61) and the second compression chamber (62) while the refrigerant compression operation is halted in the third compression chamber (63) and the fourth compression chamber (64). In a two-stage compression mode, refrigerant compressed in a single stage in each of the first compression chamber (61) and the second compression chamber (62) is further compressed in the third compression chamber (63) and the fourth compression chamber (64).

The prediction means calculate the duration of utilization of the vacuum line prior to failure of the pump unit from the measurement of a functional parameter relating to the motor provided by the first means and the measurement of a functional parameter relating to the exhaust system provided by the second means. In a variant, the vacuum line further includes third measurement means for measuring a functional parameter relating to the pump body, and the prediction means calculate the duration of use while taking account of the measurement of this parameter.

    摘要： A compound vacuum pump incorporating a screw mechanism section. The screw mechanism section comprising two externally threaded rotors mounted on respective shafts in a pump body. The rotors are adapted for counter-rotation in a first chamber within the pump body with intermeshing of the rotor threads to pump gas by action of the rotors. The root diameter of each rotor increases and the thread diameter of each rotor decreases in a direction taken from pump inlet and in which the gas is pumped. The pump additionally incorporates a roots mechanism section comprising two roots-type profile rotors also mounted on the respective shafts and adapted for counter-rotation in a second chamber within the pump body situated at an inlet end of the pump.
