UNDERWATER VEHICLE Russian patent published in 2014 - IPC B63G8/08 F03C2/00 

FIELD: transport.

SUBSTANCE: underwater vehicle contains body, propulsion motor connected via reducing gear with screw-propeller. Driven shaft of main reducing gear is connected by its one end with hydropneumomotor, and the other end of shaft is connected with screw-propeller. Hydropneumomotor contains cylindrical body closed with covers inside which a baffle plate divides body into two chambers: of forward and reverse movement, having inlet and outlet nozzles. In the hole of baffle plate a shaft is inserted. On the shaft in the first chamber forward movement rotor is mounted, and in the second chamber reverse movement rotor is mounted. Each rotor is made of set of several disks each one of which has on its end surface outer channel with rectangular cross-section, and when disks are pressed to each other internal channels are formed representing two arcs each one of which is equal to 1/4 of full circle and symmetrised relative to each other at opposite sides of rotation axis, tightly closed from one side so that plane of bottom of each one of them lays on rotor disk diameter line passing through the centre of rotation on both sides of diameter. Open portion of each arc is connected with corresponding straight channel of the same cross-section the opposite walls of which are the same in length and area, where both rectangular channels are opened to lateral surface of disk in opposite directions.

EFFECT: higher vehicle travelling speed, increased endurance.
