Abstract: There is disclosed in a refrigerant compressor whose piston stroke and thereby displacement is controlled by crankcase-suction pressure differential, a control valve that is normally responsive to at least suction pressure to control such differential but is acted on by a solenoid above a prescribed compressor speed to increase the crankcase pressure to discharge pressure to effect minimum piston stroke and thereby minimum displacement to prolong compressor life.

Abstract: Raw numerical output data representing the value of a selected function or parameter which varies according to a known relationship with one or more control functions or parameters is monitored and its measured value is normalized to determined the value, i.e., normalized value of the date under preselected standard conditions at which the control parameters have predetermined standard or nominal values. Signals representing the values of the control parameters are produced and converted to correction factor signals representing the deviations, if any, between the monitored and standard values of the control parameters, and the correction factor signals are combined with a signal representing the measured value of the raw output data to obtain a normalized data signal representing the normalized value of the output data. The data normalizing operation may occur in a test mode which provides a readout representing the normalized data value, in a monitoring mode which provides a display representing the raw and normalized data values, the monitored control parameter values, and the parameter correction factor values or furnishes these values to a computer for further processing or to a data bank for storage, or in an adaptive mode which provides error or feedback signals for regulating the control parameters to maintain the latter precisely at or within a given range about their standard or nominal values.

Abstract: A malfunction diagnosing device that includes pistons arranged in a circumferential direction and discharges oil with rotation in the circumferential direction is provided, including: a pressure sensor for detecting a pressure value of oil discharged from a hydraulic pump in rotation; a speed sensor for detecting a rotation phase of the hydraulic pump at a time when a pressure value of oil is detected by the pressure sensor; a phase calculation part; and a rendering part for rendering a model of a relationship between pressure values of oil detected by the pressure sensor and rotation phases of the hydraulic pump detected by the speed sensor and the phase calculation part to thereby obtain pulsating waveform data. This makes it possible to diagnose a malfunction of the hydraulic pump without influence of a change in a rotation speed of the hydraulic pump.
