Abstract

Hydrostatic motor with axially slidable vanes. The invention relates to a hydrostatic motor having vanes sliding axially in rotor lodgings against a continuous stator bottom surface with recesses therein. The motor comprises an intercommunication circuit between the vanes behind the latter, said circuit permitting integral transmission of pressures between vanes depending on their variable position against said recessed stator bottom surface, the vanes retracted in their lodging acting by increase of pressure in said intercommunication circuit upon the vanes projecting out of their lodging.
