ABSTRACT:
A vibrating compressor of the present invention, which comprises a piston driving section for driving a piston by supplying a piston driving force, a displacement detecting section connected in an axial direction of the piston, an upper dead point position detecting section for detecting an upper dead point position based on a piston position signal from the displacement detecting section, and a driving force control section for changing the driving force supplied to the piston by the piston driving section according to a difference between the upper dead point position and a preset upper dead point position reference value immediately after the upper dead point position detecting section detects the upper dead point position, prevents its compression efficiency from decreasing due to stabilization and prevents a device from being damaged. In the vibrating compressor, it is also possible to calculate a stroke based on a detected piston position or to control the driving force based on a detected frequency.
