The inclined inner surface and the flat surface define a recess. The plunger has a frustum portion. The frustum portion includes a flat distal surface and an annular inclined surface. The taper angle of the peripheral wall is equal to or less than twenty degrees. The diameter of the flat distal surface of the frustum portion is equal to or greater than eighty percent of the largest diameter of the annular inclined surface.

摘要： A signal transmitter apparatus generates three phase-shifted signals by shifting three transmission signals by predetermined phase shift amounts so that the phase shift amounts of the transmission signals are different from each other by 120 degrees. The signal transmitter apparatus generates three combined transmission signals and outputs the three combined transmission signals to the three transmission conductors, respectively, by combining each of pairs of the phase-shifted signals such that an inverted signal of a first phase-shifted signal is combined with a second phase-shifted signal, when each of the pairs of the phase-shifted signals includes the first and second phase-shifted signals among the three phase-shifted signals and phase shift amounts of the first and second phase-shifted signals are different from each other by 120 degrees. The signal receiver apparatus generates three receiving signals based on received three combined transmission signals, and detects the decoded signals of the transmission signals based on the receiving signals.

摘要： In a control system of a variable displacement compressor, a pressure sensing means mechanically detects at least one pressure in the refrigerant circuit. A varying means varies a reference value for positioning a valve body. A pressure detector electrically detects the pressure detected by the pressure sensing means in the refrigerant circuit and/or physical quantity which correlates with the detected pressure. A calculator calculates a maximum value of urging force applied to the valve body by the varying means toward an increasing side of the displacement of the compressor. The urging force applied to the valve body is controlled not to exceed the maximum value toward the increasing side of the displacement. The displacement of the compressor is maximized by the pressure sensing means under the pressure for calculating the maximum value when the varying means applies urging force of the maximum value to the valve body.
