Pulse Scaler
Hydraulically operated, for oil and fluid grease

The pulse scaler makes it possible to easily
divide up a centralized single-line lubrication
system into multiple lube circuits to meet
different lubricant needs.
The pulse scaler is a hydromechanically
operated rotary valve with 12 teeth in the
form of a multihole disc that is turned 1/12th
of a revolution after every lube pulse from
the main system.

Various reductions are possible depending on
the number of holes in the disc. The reductions range from 1:2 to 1:144.
The piston actuator is tensioned by the
pump’s pressure, and a spring moves the disc
in steps when the pressure is released, so
that during a respective lube pulse the lubricant can flow through to the stepped-down
system section in keeping with the scaling.

This system section can continue to relax
via the relief valve regardless of the ratchet’s
position, which can be important in case of
short actuation sequences and extended
relief phases.
