These machines usually have a constant-speed motor and a variable-displacement pump with a swash plate
that can be adjusted by the control to regulate the oil-volume flow of the pump adjusting to the current demand of the hydraulic system.
Any would-be home made helicopter designer and builder now has a valuable information resource as well as professional machinist drawings and construction plans to built some of the most elusive helicopter components such as the swash plate
which controls the helicopters flight direction by tilting the main rotor blades.
