Operation
Fig. 2
Stage 1
1 Piston (1) at rest in normal position
(† fig. 2).
2 Measuring chamber (2) filled with
lubricant from previous cycle (not under
pressure).
3 Slide valve (3) about to open under
pressure of lubricant and uncover
passage (4) leading to piston.
Stage 2
1 Slide valve (3) has now uncovered
passage (4) admitting lubricant († fig. 3).
2 Lubricant, under pressure, forces
piston (1) down.
3 Piston (1) forces lubricant from measuring
chamber (2) through outlet port (5).
Stage 3
Fig. 3
1 Piston (1) has completed full stroke. Slide
valve (3) has been forced down, shutting off
flow of lubricant to passage (4) († fig. 4).
2 Piston and slide valve remain in position
until lubricant pressure in supply line is
relieved by vent valve.
Stage 4
1 Lubricant pressure in supply line has now
been relieved by vent valve († fig. 5).
2 Spring (6) expands causing slide valve (3)
to move downward so that passage (4)
and measuring chamber (2) are connected
through outlet port.
3 Spring (6) causes piston (1) to move
upward, forcing lubricant through
passage (4) to refill measuring
chamber (2).
