Abstract
In a vane compressor wherein at least two spaces are defined between a pump housing and a rotor disposed within the pump housing, for defining pump working chambers in cooperation with vanes carried in slits in the rotor, each of the vanes has an axial end edge provided with engaging means. Arresting means is disposed for engagement and disengagement with the engaging means of the vanes. When the arresting means is in a position engaging with the engaging means, it arrests each of the vanes in a retracted position in the vane slit in the rotor, while the vane is circumferentially moving in at least one of the pump working chamber-defining spaces from a pump inlet opening in the same space to a pump outlet opening in the same space.
