Patent ID: 11608831

Abstract:
A lubricant pump for conveying lubricant from a lubricant reservoir to a pump outlet includes a pump housing with a longitudinal axis. The pump housing has a receiving opening for a pump unit, a lubricant inlet opening and a lubricant outlet opening opening into the receiving opening, a pump drive, and a pump unit with a reciprocatingly movable delivery piston. The pump unit has a suction opening, which corresponds with the lubricant outlet opening when the pump unit is inserted into the receiving opening, and an outlet opening for lubricant. A coupling mechanism for driving the at least one pump unit includes an eccentric element which is rotatable about the longitudinal axis, a drive-side coupling section connected to the eccentric element, and a pump-side coupling section. The drive-side coupling section and the pump-side coupling section can be connected to one another automatically via a resilient latching connection.
