PVM Piston Pumps PVM018020 PVM074081 Service Manual
The cyl- inder barrel in this pump is turned by the drive shaft. Pistons fitted to bores in the cylinder barrel are connected through piston shoes and a shoe plate, so that the shoes bear against an angled swash plate. As the barrel turns, the piston shoes follow the swash plate, causing the pistons to reciprocate.
