摘要:
A roller vane pump for fluid includes a carrier which is rotatable in a housing about an axis of rotation, the carrier carrying a plurality of roller vanes which are each received in a respective slot which extends inwardly of a periphery of the carrier and permits the roller to move inwardly and outwardly in use, the housing surrounding the carrier, pumping chambers being formed between the rollers, the carrier and the housing, the rollers engaging with the housing and moving inwardly and outwardly of their respective slots as the carrier rotates, in response to the configuration of the housing so that the pumping chambers change in volume as the carrier rotates, to effect pumping of the fluid, from an inlet to an outlet of the pump, and wherein in each of the slots in which the rollers are received, there is provided a restrictor element which restricts movement of the roller inwardly of its respective slot.
