MACHINE OF POSITIVE DISPLACEMENT ACTION Russian patent published in 2015 - IPC F04B19/06 F04B11/00 

FIELD: machine building.

SUBSTANCE: machine comprises cylinder 1 with differential piston 2, with creation of cavities 3 and 4 with suction 5 and 6, and discharge 7 and 8 valves. Cavity 3 is connected via the check valve 13 with additional cylinder 14 having spring-loaded piston 16 with spring 15. The cylinder is connected by channel 17 with discharge liquid line 11 via the slide valve 18 made in form of the movable rod, on one its end the compression spring 20 rests, and to the another end rope 21 from under piston cavity 4 is supplied. The orifice plate 24 is used to create the guaranteed pressure drop between the cavity 3 and discharge line 11 during the liquid discharge from the cavity 3 ensuring high uniformity of the liquid supply.

EFFECT: increased uniformity of liquid supply under any operation mode of the machine - compression and movement of liquids only, or compression and mixing of liquid and gas simultaneously.
