  • HYDRAULIC RADIAL PISTON DEVICES
    Publication number: 20160319799
    Abstract: A radial piston device (100) includes: a housing (102), a pintle (110), a rotor (130), a plurality of pistons (150) and a drive shaft (190). The radial piston device also includes a mechanism for minimizing deflection or curvature of the pintle shaft (112), which may be caused by a resulting pressure applied to the pintle shaft. In one example, the mechanism may be implemented by at least partially supporting the rotor by the housing with a bearing while the rotor is also supported by the pintle shaft with another bearing.
