ABSTRACT OF THE DISCLOSURE Lubrication Pump A lubrication pump includes a piston and cylinder pump assembly comprising a piston arranged for reciproca- tion within and relative to a cylinder and having a charging stroke and a discharging stroke, a motor drivingly connected to the piston and cylinder assembly and a priming means including a priming handle coupled to the piston and cylinder assembly. In order to reduce the risk of damage to the pump or parts of a downstream lubricant distribution system through excessively forceful use of a priming handle and to provide a visual indication of the operation of the pump, a resilient member is provided in the coupling between the priming handle and the assembly such that movement of the priming handle to move the piston relative to the cylinder through the discharging stroke can take place without corresponding movement of the piston relative to the cylinder by deformation of the resilient member.
