ADJUSTABLE AXIAL;-PISTON MACHINE Russian patent published in 2006 - IPC F04B1/30 

FIELD: mechanical engineering.

SUBSTANCE: device is designed for use in electrohydraulically controlled axial piston machines. Proposed adjustable axial piston machine contains rocking unit housing with shaft, adjusting mechanism with control piston position sender, rocking unit including inclined block rotating around axis of central journal. Pistons get into cylinders of inclined block. Distributor is provided with liquid inlet and outlet channels. Inclined block rests on distributor from one side, and distributor, from other side, rests on surface of rotation of adjusting mechanism housing and is coupled with control piston by means of pin. Control piston sender is made in form of linear transformer. Control piston is arranged in space of adjusting mechanism housing. Rod space of control piston communicated with high-pressure channel. Slot made in adjusting mechanism housing from side of surface of rotation intersects space accommodating control piston. Winding of linear transformer is arranged in slot. Control piston is made of current-or magneto-conducting material.

EFFECT: reduced overall dimensions of adjustable axial-piston machine, improved reliability in operation.
