The present application relates to a kind of
rotary compressor, gas
compression system,
refrigeration system and
heat pump system,
rotary compressor includes cylinder,
piston,
crankshaft, swing block and sliding vane, the compression chamber and swing groove are arranged inside cylinder,
piston is arranged in the compression chamber, swing block is rotationally arranged in swing groove, sliding slot is arranged on swing block, sliding vane is slidably arranged in sliding slot, and one end of sliding vane and the side wall of
piston abut, the other end between the inner side wall of the cylinder is provided with the driving
assembly for driving the one end of the sliding vane and the side wall of the piston abut,
crankshaft is linked with piston, and drives piston to eccentric rotation in the compression chamber, swing block is synchronously swung back and forth in swing groove. By the sliding vane and the rocker block of prior art are designed as a whole, the swing amplitude of sliding vane and swing block can be greatly reduced, the friction
power consumption is effectively reduced, and the cold leakage between sliding vane and piston can be reduced, the
lubrication state between swing block and cylinder is improved, and the
friction loss between sliding vane and cylinder is reduced.
