| 摘要 |
A pump comprising a supporting structure including a bearing support, a wobble plate, a bearing between the bearing support and the wobble plate for permitting the wobble plate to nutate and for transmitting radial loads from the wobble plate to the bearing support, a cam rotatably mounted on the supporting structure for causing the wobble plate to nutate, and a mechanism for drivingly coupling the cam to a shaft of a motor. Radial loads are transmitted by the bearing to the supporting structure rather than to the cam. The wobble plate is coupled to a suitable output device such as the diaphragm of a diaphragm pump.
