Title: Compressor and method of controlling the same
Inventor: JOO JAE-MAN
IPC: F04B49/06
Filed: 2001-12-11
Abstract: PROBLEM TO BE SOLVED: To provide a compressor capable of facilitating the drive control of a drive device for reciprocating a piston by improving the drive device to make the product further compact, and a method of controlling the compressor. SOLUTION: The drive device 30 for driving the piston 23 consists of an elastic member 31 and piezoelectric actuators 32. The position of the edge part of the elastic member 31 is determined relative to a cylinder block 21 so that the elastic member 31 can oscillate upward/downward, and the piston 23 is mounted on the elastic member 31. The piezoelectric actuators 32 are disposed on the elastic member 31 for applying the oscillation force to the elastic member 31 by repeatedly deforming as the electric power is applied. Therefore, the drive device 30 of the piston 23 can be made compact to reduce the size of the product on the whole. In addition, the displacement of the piston 23 is sensed via the piezoelectric actuators 32, and the desired output can be more easily adjusted by controlling the voltage applied to the actuators.  In this case, an additional displacement sensor is not required for sensing the displacement of the piston 23 and the elastic member 31.
