Summary:The present disclosure provides an oil-scavenge pump, which includes a cap member, a piston member, a resilient member and a filter member. The filter member interconnects the cap member and the piston member. The resilient member is disposed between the cap member and the piston member. The cap member includes a cap head, a pump valve connected to the cap head, a first-resilient unit disposed and a first sphere disposed between the first-resilient unit and the pump valve. The piston member includes a main portion, a piston seat, a second-resilient unit, a second sphere and a rod portion. The piston seat has two ends respectively connected to the piston head and the rod portion. The second-resilient unit and the second sphere are disposed between the piston head and the piston seat. The filter member is mounted to surround the rod portion and engaged with the pump valve.
