ENGINE RUNNING ON FLUID WITH IMPROVED BRAKING PROPERTIES Russian patent published in 2012 - IPC F01C21/00 F01C1/344 

FIELD: engines and pumps.

SUBSTANCE: engine rotor 20 is driven by compressed fluid. Compressed fluid expands in engine working chamber 18. Rotor braking element 22 is arranged axially with said rotor. Element 22 and rotor 20 displace axially relative each other to make spring-loaded friction pair 48, 50. Higher braking effect is ensured by springs 52 and compression chamber 60, its crosswise length exceeds that of working chamber 18. Chamber 60 is limited, at least, one axial side by element 22. Pressure in chamber 60 and between element 22 and rotor face side creates force to disengage aforesaid pair 48, 50 on overcoming force of springs. Chamber 60 is arranged to force compressed fluid in chamber 60 on loading engine 20. Fluid fed to rotor 20 acts on element 22 adjoining face surface 50 of rotor 20 create aforesaid disengagement force. Pressure in chamber 60 creates extra disengagement force, opposite that of springs.

EFFECT: better braking effect.
