Abstract: An area of an inlet end (51) of the discharge port (50) is Ai; a peripheral length of the inlet end (51) is Li; and a hydraulic diameter of the inlet end (51) is defined by Di = 4(Ai/Li). A peripheral length of the outlet end (52) of the discharge port (50) is Lo; a reference lift amount of the valve body (61) is ho; a cross sectional area of an outlet side flow path (70) formed between the outlet end (52) of the discharge port (50) and the valve body (61) is defined by Ao = Lo × ho; and a hydraulic diameter of the outlet side flow path (70) is defined by Do = 4(Ao/2Lo). A ratio (Do/Di) of the hydraulic diameter Do of the outlet side flow path (70) to the hydraulic diameter Di of the inlet end (51) of the discharge port (50) is 0.5 or less. As a result, the lift amount of the valve body (61) is optimized, thereby improving the efficiency of the compressor.

Abstract: A control valve of a variable displacement compressor is disclosed. The control valve includes a valve housing, a valve body, a valve opening spring, an electromagnetic actuator, and an urging plate. The valve housing has a valve chamber that forms a part of a supply passage. The valve body can selectively contact and separate from a valve seat in the valve chamber. The valve opening spring urges the valve body away from the valve seat. The electromagnetic actuator changes electromagnetic urging force acting on the movable iron core through control of externally supplied current. In a state where the electromagnetic actuator is not energized and the valve body is held at a position separated from the valve seat by the urging force of the valve opening spring, the urging plate deforms in such a manner as to urge the valve body toward the valve seat when the temperature of the urging plate reaches a predetermined temperature. The urging force of the urging plate when the temperature reaches the predetermined temperature is set to be greater than the urging force of the valve opening spring in a state where the electromagnetic actuator is not energized.

Abstract: Load sharing is achieved in a multiple compressor system by a program in a computer which sends signals to, and receives data from, a microcontroller located at each compressor. One compressor, designated as the lead compressor, furnishes its operating parameters, via the computer, to all the other, lag, compressors. The operating parameters include inlet valve position and bypass valve position of each compressor and the microcontroller controls the actuation of both valves. When system demand decreases, compressors are gradually unloaded, and then stopped to go off-line. When system demands increase, compressors are first started, and then gradually loaded before going on-line. Compressors go both on-line and off-line subject to certain time delays so that compressors are gradually added to, or shed from, the load. To equalise running time, all compressors in the system may undergo a periodic rotation and compressors go off-line in reverse order that they came on-line.

Abstract: A method for detecting a blocked valve of a coolant compressor (1) comprising a drive unit (4) and a piston-cylinder unit for cyclical compression of a coolant, wherein the drive unit (4) has an electric motor for driving the piston-cylinder unit, wherein the speed (ω) of the electric motor is monitored. According to the invention, a maximum speed (ωmax) of the electric motor is initially detected, and the following steps are carried out, as long as the speed (ω) of the electric motor substantially corresponds to the maximum speed (ωmax): determining a maximum value Xmaxof a monitoring parameter (I, T) of the coolant compressor (1); determining a value Xt1of the monitoring parameter (I, T) after a first time period (t1) after determining the maximum value Xmax; detecting a blocked valve if Xt1 is less than Xmax and (Xmax- Xt1) / Xmax≥ Δx applies, wherein Δx is predetermined.
