RADIAL-PISTON PUMP WITH RIGID CONNECTION OF CONNECTING ROD WITH PISTON Russian patent published in 2016 - IPC F04B1/04 F04B9/04 F04B53/14 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, particularly, to radial-piston pumps used for injection of fluid with high pressure. Pump with rigid connection of connecting rod with piston includes housing 1 with at least one cylinder 2, in which to form working chamber 3 is made integral with con-rod 4 piston 5 to support 6 and sealing elements 7. In contact with cylinder edge 8 and 9 support and sealing elements adjoin each other and lie in planes perpendicular to axis of piston. Branching off them conic surfaces are made with angles β, larger than maximum angle γ of inclination of piston in cylinder.

EFFECT: simple and compact design, minimum losses for friction and high efficiency, serviceability at low-viscosity and poorly lubricating liquids and gases of high pressure.
