ABSTRACT:
An axial-piston hydraulic machine with a rotating cylinder block. The axial bores of said cylinder block accommodate reciprocating pistons. Said pistons restrict the working chambers some of which communicate through a passage with a high-pressure zone while the others communicate through a passage with a low-pressure zone. The surface of each working chamber at its minimum volume is spherical and merges smoothly with the passage.
