摘要:
A refrigerant compressor assembly (10) for a refrigeration circuit controls the temperature within a temperature controlled space (11). The refrigerant compressor assembly includes a first unloading valve (26), a first valve actuator (92), and a first valve control system (96) that adjusts the first valve actuator via a pulse-width-modulated signal, a second unloading valve (30), a second valve actuator (140), and a second valve control system (144) that adjusts the second valve actuator via a pulse-width-modulated signal. The refrigerant compressor assembly (10) also includes a third unloading valve (34). The first valve actuator (92) is coupled to the first (26) and third (34) unloading valves and controlled by the first valve control system (96). The unloading valves selectively allow or resist fluid flow from higher to lower pressure areas within the refrigerant compressor assembly.
