FIELD: engines and pumps.
SUBSTANCE: lubricator consists of a pump with piston body and a piston. The piston body extends from the first end to the second end, and it has a drilled hole, going through the piston body from the first end of the piston body to the second end of the piston body. The piston body also has a recess, located at the second end of the piston body, herewith the recess is concentric, relating to the drilled hole, and its diameter is larger, than the diameter of the drilled hole. The piston is located in the drilled hole of the piston body. The piston body recess and the area around the piston has at least one elastomer seal. The piston may be coupled with the rocker arm unit by the ball joint. There is the liquid channel and the return valve inside the piston.
EFFECT: invention provides the pump reliability increase.
