FIELD: engines and pumps.
SUBSTANCE: at compression stroke in first cylinder, air or fuel mix press against compressor drive piston end surface to drive compressor piston so that working fluid is displaced via check valve into hydraulic accumulator. At a time, fluid from compensation tank is fed via check valve into opposite chamber. After first cylinder piston reached TDC in second cylinder at compression step or at fuel combustion step and expansion of combustion products, air, mix or combustion products press against second cylinder compressor drive piston end surface. This makes compressor drive piston displace the compressor piston engaged therewith to feed working fluid from opposite chamber via check valve into hydraulic accumulator. Thereafter, this cycle reiterates.
EFFECT: unified drive for control over valve body and fuel atomiser.
