Abstract

PURPOSE: To improve characteristics of slant plate type axial piston pump-motor by increasing press force between cylinder plate and valve plate in such a way that a sleeve of diameter larger than that of piston is inserted in enlarged cylinder chamber of cylinder block.
CONSTITUTION: Sleeve 3 of which diameter dS is made larger than diameter dP of piston 2 is inserted in enlarged chlinder chamber 1a at one end of cylinder bolck 1. Namely, since sleeve diameter dS is larger than piston diameter dP, press force between cylinder plate 4 and valve plate 5 can be increased. Accordingly, width of seal land and breadth of port opening can be freely designed as will within the range of increased press force so that charasteristics of slant plate acting as pump- motor can be improved.
