FIELD: pumps.
SUBSTANCE: invention relates to hydraulic pump. Pump (10) comprises housing (12) accommodating rotor (14). Housing (12) and rotor (14) interact with each other to form chamber (16) for fluid medium between them. Housing (12) includes first and second outlets (30a, 30b), each of which is located in communication with corresponding first or second section (32a, 32b) of chamber (16). Housing (12) is movable relative to rotor (14) for changing relative size of first and second sections (32a, 32b). Pump (10) includes control unit (36) configured to move housing (12) relative to rotor (14). Unit (36) comprises control unit (62), which is connected to drive (64). Drive (64) includes housing (66) and rod (68), which is movable in and out of housing (66). Drive (64) includes lever (70), which connects stock (68) with housing (12).
