Title:
VIBRATION TYPE COMPRESSOR
Document Type and Number:
Japanese Patent JP3717961
Kind Code:
B2
Abstract:
PURPOSE: To provide a vibration type compressor generating no over-stroke of a piston.
CONSTITUTION: This vibration type compressor 15 constitute o a displacement detector 21 connected in the axial direction of a piston 14, a converter circuit converting AC power into DC power, an inverter circuit converting DC into AC and applying a voltage to a coil by switching transistors, a top dead center position calculating means calculating the top dead center position of the piston 14 based on the piston position signal from the displacement detector 21, and an amplitude control means changing the output voltage of the inverter circuit in response to the difference between the top dead center position and the top dead center reference value set in advance.
