Pendulum-slide pump e.g. oil pump for pumping fluid e.g. oil to internal combustion engine of motor vehicle, has internal rotor and external rotor which are constructed with two inner rotor discs and outer rotor discs respectively
The pendulum-slide pump (1) has an internal rotor (2) which is rotatably mounted inside to communicate with an external rotor (4). The external rotor is connected with a pendulum (3). The internal rotor and the external rotor are constructed with the two inner rotor discs (10) and the outer rotor discs (11) respectively. The inner rotor discs and the outer rotor discs are secured together by welding such as laser welding or electron-beam welding. The inner rotor discs and outer rotor discs are made of steel sheet.
