Abstract

PURPOSE: To improve the efficiency of the said pump by forming the shape of a vane groove on flow-in and -out surfaces into a trapezoid which is inclined in the direction of revolution.
CONSTITUTION: The shape of a vane groove on flow-in and -out surfaces 7 and 8 is formed in a trapezoid which is inclined in the direction of revolution. This removes the dead water region in the vane groove and the inlet and outlet losses in the vane groove. As a result, the efficiency of the said pump can be improved.
