LINEAR DRIVE AND LINEAR COMPRESSOR WITH VARIABLE POWER Russian patent published in 2011 - IPC F04B35/04 

FIELD: machine building.

SUBSTANCE: linear drive (2) has stator (4) and slider (5) performing reciprocal motions inside stator along axis (9) of drive between first (11) and second (12) points of slider return relative to zero position (13) of slider and/or with linear compressor (3). The compressor has piston cylinder (7) and piston (6) actuated into motion with linear drive (2). The piston performs reciprocal motion inside the cylinder along axis (8) of the piston between first (21) and second (22) points of piston return relative to zero position (23) of the piston. Zero position (13) of the slider or zero position (23) of the piston can be regulated and/or at least one flexible element (14, 15) actuates either slider (5) or piston (6) of the compressor. Length of the flexible element can be changed, in particular, shortened and/or its coefficient of elasticity, in particular, can be increased. Regulation of power generated with the device does not essentially influences electro-mechanic efficiency of the device.

EFFECT: manufacture of linear drive and linear compressor with essentially less expenditures due to considerably reduced number of types of components.
