METHOD OF REDUCING ELECTRIC POWER CONSUMPTION OF QUICK-ACTING DISTRIBUTOR AND DEVICE TO THIS EFFECT Russian patent published in 2008 - IPC F15B13/44 

FIELD: engines and pumps.

SUBSTANCE: method and device are intended for control system operated by gaseous working medium. The method consists in the following. With the switched off electromagnetic drive windings, the armature is set at its travel centre, and, during drive operation, electromagnetic forces are induced on the armature each side in turn. Here, air being distributed is forced to blast the electromagnetic drive stator and windings to create equal in size and opposite-sign forces acting on the armature along its travel. The distributor is made up of two concentrically located cylinders jointed by a connector in their central zone. Coils with windings are arranged between cylinders on both sides of the connector with a gap for air to pass through. The smaller diameter cylinder accommodates a cylinder rod making a dual-action armature with blind holes on its every end to accommodate the springs resting against the covers, thus retaining the rods with an equal clearance relative to covers. The cylinders walls have two rows of inclined holes symmetric relative to the connector jointing the cylinders.

EFFECT: lower electric power consumption.
