Abstract
A hydrostatic motor unit is provided having two hydraulic motors located coaxial to each other. The motor unit includes a radial piston motor which has a constant absorption volume, is internally pressurized and has multiple-stroke capability, and a reversible axial piston motor that employs a swash plate construction and has a variable absorption volume and is located axially adjacent the radial piston motor.
Claims21
