DEVICE FOR SHIFTING TYPE MACHINE, CONTROL GEAR DRIVE FOR DEVICE AND USE OF CONTROL GEAR DRIVE Russian patent published in 2020 - IPC F01C1/77 F04C2/77 F04C18/77 F02B53/00 

FIELD: machine building.

SUBSTANCE: device for biasing machine comprises two parts. First part inside has two inwards blades with mutual angular distance. Second part has hub, which has two outward directed blades with mutual angular distance, wherein the hub portion between the blades of the second part is in sliding contact or in close proximity to the curved free end portion of the blades on the first part. Curved free end section of each blade on other part is in sliding contact or in close proximity to curved inner wall on first part, which is located between corresponding one of two adjacent blades on first part, wherein blades of second part can move between corresponding adjacent blades on first part so that chambers, which are formed between interacting pairs of blades on first part and second part, are sequentially increased and decreased, respectively, in volume during rotation cycle of formed chambers, and wherein movement of said jointly moving parts takes place under action of control gear, which operatively interacts with rotating main drive shaft of machine.

EFFECT: simplified design of the device.
