摘要： A method of driving an engine valve-driving electromagnetic valve, wherein a permanent magnet is provided in a movable element of the electromagnetic valve, and springs are omitted, and wherein repulsion and attraction electric currents are varied according to the engine speed, thereby reducing the electric power consumption. The permanent magnet is magnetized in the axial direction. When the repulsion current is passed through one exciting coil, the attraction current is passed through the other exciting coil, thereby moving an engine valve to an open position. When the attraction current is passed through the one exciting coil, the repulsion current is passed through the other exciting coil, thereby moving the engine valve to a closed position. In the low-engine speed region, the current value is smaller and the energization time is longer than in the high-engine speed region.

摘要： A two-stage screw compressor of the invention includes a low pressure stage casing provided with a low pressure stage compression mechanism, a discharge casing provided on a discharge side of the low pressure stage casing, a high pressure stage casing provided with a high pressure stage compression mechanism, and intermediate stage casings for connecting the discharge casing and the high pressure stage casing, and accommodating an electric motor. In such a two-stage screw compressor, a cavity is formed on a discharge casing side in the slide valve so as to enlarge the capacity of a discharge space formed in the discharge casing. Thereby, internal resonance occurring in the discharge casing is prevented.
