Abstract

The hydraulic pump comprises a casing (2) comprising a blade wheel (3) mounted on a driving shaft (4). The casing delimits a flow channel for the fluid between an inlet (5) and an outlet (6). There are wheel and fluid male and female ramp guides (7,8) able to selectively engage or separate the wheel and the flow channel. An Independent claim is included for a cooling circuit.
