Abstract

The regenerative type feed is for a pump used in the hydraulic control circuit of a car automatic gearbox. The pump is engine driven and there is a pressure regulator joined to the pump intake by an injector. This injector is between the regulator and the pump. The injector can be inside the pump intake pipe and is directed in the same direction as the pipe. It can be placed inside a venturi, working with the injector. This venturi has a circular section or one slightly flattened, or an oval one.
