Discussion Structure of Variable Displacement of Double Action Vane Pump
This paper discusses the configuration and the action principle of a new variable displacement of double-action vane pump, which consists of floating blocks. The floating blocks that may move up and down in accordance with the rotational speed of the pump. The pump belongs to an automotive hydraulic power steering system, and prosperous utilization is expected. The theoretical flow model of the new pump was established and the pump flow changes under different speed were compared.
