Abstract

A fluidic-type material is contained in a main or working sump 4. Sump 4 is adjacent to a reserve sump 6 and is inter-connected by means of normally closed flow control valve 8. As the material circulates through the particular system and is recycled through the working sump, some material may be lost, If the pressure drops low enough in sump 4, pressure in sump 6 forces the flow valve 8 to open permitting reserve material to be added to the working material until the pres-sure reaches the former equilibrium; and valve 8 again is forced into the closed position. This cycle would be repeated until the reserve sump is exhausted.

connected by means of normally closed flow control valve 8.
As the material circulates through the particular system and
is recycled through the working sump, some material may be
lost, If the pressure drops low enough in sump 4, pressure in
sump 6 forces the flow valve 8 to open permitting reserve
material to be added to the working material until the pres-
sure reaches the former equilibrium; and valve 8 again is
forced into the closed position. This cycle would be repeated
until the reserve sump is exhausted.
