Step 5
n Piston D opens the channel to the left-hand side of piston A.
n The lubricant presses the piston to the right. The lubricant in front of the piston is
pressed out through output 1.
n Pistons B to D are then moved in order from left to right.
n A complete lubrication cycle has now been completed and will begin again.

When lubricant flow has been interrupted
n The pistons stop
n No lubricant reaches the lubrication points
n When the flow starts again, the pistons begin to move from the exact spot they
stopped.
Functionality check
n The primary distributor (Fig. 23) and secondary distributors are connected with main
lines (G). The pump is connected to the primary distributor.
n If a piston in any of the blocks gets jammed or if an output is blocked, the lubricant dis-
tributor will stop.
n Thanks to the design of the system, a blockage in the primary distributor will propagate
and the entire lubrication system will stop (all pistons in all distributors stand still).
n The simple design also ensures that a blocked lubrication point is never forgotten.
n Since the pump is still pumping out lubricant and the distributors have stopped, the
lubricant must go somewhere. Pressure in the system increases and the block be-
comes apparent when lubricant leaks from the safety valve (Fig. 25).
