Automatic motor driven in-line piston pump lubricator

摘要

In various embodiments, the invention provides a lubricator comprising a housing defining, a main lubricant chamber adapted to contain a fluid lubricant. A piston pump in fluid communication with the main lubricant chamber may be adapted to be driven to discharge the lubricant from a pump changer through a lubricant outlet in the housing. A check valve may be mounted on the lubricant outlet, to check the discharge of lubricant from the lubricator. The lubricator may include a motor having a drive shaft adapted to rotate a swash plate to act as a cam to drive reciprocating motion of the pump piston in the pump chamber. The drive shaft may be in axial alignment with the piston, the swash plate being set obliquely on the drive shaft to revolve when the motor is activated to give reciprocating motion to the piston in a direction parallel to the driven shaft. The piston may be biased in the pump chamber against the swash plate, so that the swash plate rides on the piston.

1. A lubricator comprising:
i) a housing defining a main lubricant chamber adapted to contain a fluid lubricant, the housing having a lubricant outlet for discharging the lubricant from the lubricator; ii) a piston pump in fluid communication with the main lubricant chamber, the piston pump comprising:
a) a pump chamber adapted to receive the lubricant from the main lubricant chamber; and,b) a pump piston adapted to be driven to discharge the lubricant from the pump chamber through the lubricant outlet in the housing; iii) a motor for driving the piston pump, the motor having a drive shaft in axial co-alignment with the pump piston and adapted to rotate a cam about an axis of rotation, wherein rotation of the cam about the axis of rotation causes a cam surface of the cam to ride on the pump piston along a path on a surface of the pump piston, the path having varying heights, relative to the pump piston, along the axis of rotation and the cam surface having varying heights, relative to the drive shaft, along the axis of rotation such that rotation of the cam about the axis of rotation causes the cam to drive reciprocating motion of the pump piston in the pump chamber; iv) a means for urging the fluid lubricant into the pump chamber; and, v) electronic controls for regulating the activation of the motor to control the discharge of the lubricant from the lubricator.
