Abstract

A fluid-tight seal between each cylinder bore in the barrel of a swash-plate pump and the corresponding port bore in a port plate rotating with the barrel is established by a sleeve, which is accommodated in aligned counterbores of the two bores, provided at the mutually adjacent end faces of the barrel and port plate, and which is sealed in each of these counter bores by a separate compressed O-ring seal, common rotation of the port plate with the barrel being ensured by means independent of the sleeves. The sleeve has sufficient play in the counter bores to allow for slight angular displacement between the respective end faces of the cylinder barrel and the stationary valve face of, for example, a valve plate. Preferably the O-rings are accommodated in annular recesses at each of the two ends of the sleeve and are compressed axially between washers resting respectively against the bottom shoulders of the two counter bores so that the resilience of the O-rings provides an axial thrust force urging the port plate into contact with the valve plate.
