AXIAL HYDRAULIC MACHINE Russian patent published in 2007 - IPC F04B1/20 

FIELD: hydraulic power plants.

SUBSTANCE: proposed axial hydraulic machine has housing with fitted-in piston pairs with ball hinge-secured in spherical sockets. Spherical seat and commensurable ball support for ball heads of piston pairs are installed in housing space for synchronous angular rotation around its axis to provided, at angular rotation, kinematic coupling with communicating spaces of spherical seat and ball support forming static volume working chambers. In end faces of drum spherical seats can be installed with commensurable ball supports for ball heads of cylinders and pistons installed on shafts and forming piston pairs coupled for synchronous angular rotation by means of toothed rims with equal number of teeth. Static volume working chambers are formed by spaces of spherical seats and ball supports with piston pairs communicating through spaces of drum.

EFFECT: possibility of use of device as hydraulic motor and hydraulic pump in one working cycle.
