DEVICE FOR CREATION OF PRESSURE FLOW OF WORKING FLUID Russian patent published in 2011 - IPC F04B19/24 F04B9/08 F04B43/06 

FIELD: machine building.

SUBSTANCE: device for creation of pressure flow of working fluid consists of at least two groups of high pressure vessels with heat exchanging system. Each vessel is divided with a movable pressure tight partition into two parts. One part is filled with working substance changing volume at phase transition. Another part is filled with working fluid. Each group of vessels operates independently under a heating or cooling mode. The part of each vessel of high pressure containing working substance is made as a tubular capsule with developed heat exchanging surface. The movable pressure tight partition is made in form of a combination of a plunger contacting working substance and of a piston of bigger, than the plunger, diametre, contacting working fluid, or in form of an elastic heat resistant tube placed inside the tubular capsule along its lengthwise axis.

EFFECT: decreased dimension of structure, simplification of manufacture and operation, versatility of application.
