Lubrication system

摘要

A lubrication system (50) for a vibratory apparatus such as a hydraulic striking device. The system (50) includes a lubricant pump (1) for pumping lubricant to one or more points of lubrication on the device and a drive for the pump powered in response to vibration of the device. The system (50) includes a base for attachment to the device for vibration therewith, and a lubricant pump (1) for pumping lubricant from a supply. The pump (1) includes a cylinder and a plunger reciprocable in the cylinder through a strike between a retracted position for intake of lubricant into the cylinder and a forward position for delivery of the intake from the cylinder. A weight (3) is mounted on the base for oscillation in response to the vibration of the device, oscillation of the weight effecting reciprocation of the plunger through a stroke.
