During compressor 10 operates, regulating system 27 can recycle between active state and non-applied state.With regard to this
For, being provided to the electric current of displacement member 152 can utilize pulse width to modulate in " connecting (on) " and " disconnecting (off) " shape
It is recycled between state.Cycle between " on " and "off" state causes regulating system 27 in capacity operation condition and unloading
It is recycled between (such as unloaded) operating condition, to reduce and/or otherwise control the operation discharge capacity of compressor 10.
In some configurations, displacement member 152 can be piezoelectric material or including piezoelectric material, supplied to displacement member
152 electric current can make displacement member 152 activate its piezoelectricity shape memory characteristic with by hub 150 and determine vortex 106 relative to dynamic whirlpool
Revolve 104 axially displaced (that is, reaching idle position).When operating temperature is less than threshold operative temperature, displacement member control mould
Block 153 removes electric current so that displacement member 152, hub 150 and determine vortex 106 are back to fully loaded position from displacement member 152.
In another example, displacement member 152 can be magnetic shape memory materials, and displacement member control module 153 can
To provide magnetic field to displacement member 152.Magnetic field can make displacement member 152 activate its magnetic shape memory characteristic so that 150 He of hub
Determine vortex 106 is axially displaced (that is, reaching idle position) relative to dynamic vortex 104.When operating temperature is less than threshold operative temperature
When spending, displacement member control module 153 removes magnetic field so that displacement member 152, hub 150 and determine vortex 106 from displacement member 152
