Abstract
A scroll machine has a fluid path which is defined by two components of the scroll machine. The fluid path extends between a discharge pressure zone and a suction pressure zone of the scroll machine. The scroll machine further includes a biasing member which biases one of the two components away from the other of the two components to open the fluid path when the scroll machine is not operating. The effect of the biasing member is overcome by several revolutions of the scroll machine by centrifugal force in one embodiment and fluid pressure in another embodiment.
