RECIPROCATING LIQUID MACHINE Russian patent published in 2007 - IPC F01B9/00 

FIELD: power engineering.

SUBSTANCE: invention is designed for use in power engineering as liquid device with triangular connecting rod provided with decoupling of pistons and in which each piston is furnished with its own pair of sliding surfaces and its own slider. Sliding surfaces of each piston are arranged at one side relative to support of lower end of connecting rod located on crank. Main axle of crank is made for travel along definite path which provides practically no lag or advance of piston. Effective center of masses of crank, piston and slider is motionless to axis of crank. Each piston includes guide to preclude movement of piston in direction other than along axis of piston. Guide is arranged across sliding surface and is made for engagement with guide members rigidly installed on case. Intermediate connecting device is provided which is made with possibility of connection of piston and sliders with means to adjust position of intermediate connecting device to change compression ratio of device. In device with pistons arranged opposite to each other, connecting rod unit connected to two pistons is split in two parts which are held together with possibility of detachment.

EFFECT: provision of dynamic balancing and possibility of use of odd number of pistons.
