Description

Technical Field

[0001] The utility model relates to the technical field of bidirectional oil pumps, in particular to a forward and reverse equal-amount oil supply device for a bidirectional oil pump. Background Art

[0002] A bidirectional oil pump is a pump that transports liquid by relying on the change in working space volume generated by the mutual meshing of two or more gears sealed in a housing.

[0003] After searching, the announcement number CN210739734U is found to be a conveniently movable bidirectional oil pump, including a pump and an electric motor, the output shaft of the electric motor being connected to the input shaft of the pump, and also including a movable seat, the bottom end of the movable seat being fixedly connected to four groups of rollers, a push rod being provided on the upper part of the movable seat, two groups of slide grooves being respectively provided on the two side wall surfaces of the movable seat, each of the slide grooves being slidably connected to a group of fixing devices, the bottom ends of the electric motor and the pump being fixedly connected to a fixed plate, the fixed plate being located above the movable seat, and a shock-absorbing layer being fixedly connected between the fixed plate and the movable seat.

[0004] In response to the aforementioned related technologies, the inventors believe that existing bidirectional oil pumps can only supply oil in one direction during use.
