Continuously variable displacement pump with predefined unswept volume |
摘要 |
Apparatus and method for controlling an unswept volume in a piston system. The method includes rotating a shaft around a rotation point to drive a piston within a cylindrical volume in a periodic manner, modifying the stroke length of the piston, and moving the center of the shaft relative to the cylindrical volume such that a change in an unswept volume or compression ratio is controlled.
