HYDROPNEUMATIC TURBOMACHINE (VERSIONS) Russian patent published in 2006 - IPC F01C7/00 

FIELD: mechanical engineering.

SUBSTANCE: invention can be used in steam and gas turbine engine, expansion and compressor machines and internal combustion engines. Proposed hydropneumatic turbomachine contains sealed cylindrical housing partially filled with liquid, gas or air supply and outlet systems, working liquid supply and outlet systems, wheel with blades and distributor. Wheel with blades is installed in housing eccentrically for rotation. Blades of wheel form channels to which distributor adjoins from side of shaft. Channels to supply and let out gas or air, supply of liquid, supply of fuel-air mixture, fuel nozzles, ignition plugs and primers are made in distributor. Wheel adjoins from two opposite sides with clearance to two cutoffs for periodical overlapping of curvilinear channels at rotation of wheel. One of cutoffs is formed by wall of sealed housing, and the other is installed in widest part of crescent-shaped space of housing. Mounted between wall of housing and cutoff installed in widest part of crescent-shaped space from one side of cutoff is input of hydraulic turbine when hydropneumatic turbomachine operates as expansion machine or pump input when hydropneumatic turbomachine operates as compressor. Outlet of said turbine or pump is made from other side of cutoff between cutoff and housing wall. According to other design version, wheel adjoins, with calibrated clearance, to two cutoffs are formed by walls of housing from two opposite sides for periodical overlapping of two opposite channels at rotation of blade wheel and they divide sealed housing into minimum two crescent-shaped spaces. Cutoff is made in widest of each crescent-shaped space. Mounted between cutoff and housing wall in widest part of each crescent-shaped space of housing from one side is input of hydraulic turbine, when hydropneumatic turbomachine operates as expansion machine or pump input, when hydropneumatic turbomachine operates as compressor. Outlet of said hydraulic turbine or pump is fitted-in from other side of cutoff. Hydraulic turbine or pump is either installed on shaft of bladed wheel, or is mechanically connected with shaft.

EFFECT: simplified design of turbomachine.
