Hydraulic device with a lubricating pump

Abstract

The invention relates to a hydraulic device with a supply line for pressurized hydraulic fluid and with a lubricating pump that is connected to the supply line in a fluidic fashion. The lubricating pump comprises a hydraulic inlet, a pump element for conveying a lubricant from a reservoir to at least one lubricating point of the hydraulic device, and mechanism for producing a pump stroke of the pump element. The mechanism for producing a pump stroke comprises a base body, a piston unit movable in the base body, and a reversing mechanism for reversing the direction of movement of at least one element of the piston unit. The reversing mechanism comprises at least one bypass formed by at least one recess, and at least one elastic element acting upon the piston unit in a first direction oriented toward the hydraulic inlet whereby the piston unit can be displaced in the base body in an oscillating fashion between a closed position in which a fluid connection between the hydraulic inlet and the hydraulic outlet is blocked, and an open position in which said fluid connection is unblocked in order to produce a pump stroke of the pump element.
