Abstract:
A gear pump capable of alternately distributing a fluid in two distinct utilization circuits without the need for a switch. The gear pump (1) comprises two fluid outlet ports (5, 6) connected to two fluid utilization circuits and linked to the discharge chamber (C) of the pump via an integrated commutation (7). These commutation (7) comprise two distribution circuits (50, 60), located in a fixed support plate (70), and two buffer channels (30, 40), located in the rotary toothed wheels (3), arranged so as to alternately open and close the distribution circuits according to a commutation cycle that approximately corresponds to the rotation of the toothed wheels over half a revolution.
