Abstract

The invention relates to a toothed wheel pump used in the hydraulic drives of machine tools. According to the invention, the pump consists of a box with two inner toothed wheels, each of them provided with radial channels corresponding to the empty spaces between teeth and an adjustable position axial drawer. Each axial drawer has several circumferential channels of different sizes, both drawers being axially adjusted through some rods that have a crimped ball at their end, towards the drawer. Both rods are fastened in a support provided with a wheel on which presses a tronconic bushing, mounted on a piston rod directly connected to the pump discharge mouth, the other end of the piston rod being operated by an adjustable spring.
