WIPO Patent Application WO/2024/007904
Kind Code:
A1
Abstract:
An elastically driven piston pump, comprising a cylinder block, a spring, a first piston, a first rotor, a first rod member, a second piston, a second rotor, a second rod member, and an eccentric transmission shaft. The eccentric transmission shaft is disposed on the cylinder block, the first rotor and the second rotor are both disposed on the eccentric transmission shaft, the first rod member is disposed on the first piston, the second rod member is disposed on the second piston, one end of the spring is disposed on the first rod member or the first piston, and the other end of the spring is disposed on the second rod member or the second piston. When the first rotor rolls or slides on the first piston to drive the first piston to move downwards, the spring drives the second rod member and the second piston to move downwards, and when the second rotor rolls or slides on the second piston to drive the second piston to move upwards, the spring drives the first rod member and the first piston to move upwards.
