Abstract
A fluid displacement apparatus includes a cam rotor connected to a drive shaft and having a first arm extending therefrom. A plate is tiltably connected to the drive shaft. The plate has a surface disposed at an adjustable inclined angle relative to a plane perpendicular to the drive shaft and has a second arm extending therefrom. The plate and the piston are coupled, so that the pistons are driven in reciprocating motion within the cylinders upon nutation of the plate. A pin member is disposed in the second arm of the plate. An engaging device is disposed in the cam rotor. The pin member is slidably disposed in the engaging device, so that the cam rotor is coupled to the slant angle for permitting the inclination of the slant plate to vary.
