At the top of their stroke, the pistons move over the inlet port and
draw in fluid at low pressure. The fluid is then carried round and expelled
through the outlet port at high pressure as the swash plate drives the
piston into the cylinder.
To demonstrate this principle, Sphaera's interactive hydraulic swash
plate pump features 8 revolving cylinders that provide a clear indication
of hydraulic pressure and flow.
Operation can be viewed at fast or slow
