BOOSTER Russian patent published in 2009 - IPC B66F3/00 

FIELD: transport, mechanics.

SUBSTANCE: proposed booster comprises casing with cover, hollow piston, plunger, rocker with a handle, check and bypass valves. Note that the said hollow is mounted in the casing to form chamber between its bottom and that of the casing. Lifting force acting on the piston bottom is created by the working body representing set of equal-diameter balls. Working body ball central part is made from magnetically soft ferromagnet, for example, steel, and coated with composite material layer. The said material can be based on epoxy binder incorporating filler made of particles of magnetically hard ferromagnet, for example, rare-earth metal-based alloy. Note that each of the said particles is magnetised and has one pole, for example, N oriented towards the ball centre and the other, S-pole, oriented in opposite direction along normal line the ball surface. All booster parts are made from non-magnetic materials, for example, stainless steel, copper alloys, ceramics or plastics.

EFFECT: multiple increase in actuating force.
