  • Hydraulic cylinder device and boat propelling apparatus including the same
    Patent number: 8707854
    Abstract: A trim device includes a trim cylinder, a piston, a piston rod and a support member. The piston is slidable inside the trim cylinder, in the axial direction of the trim cylinder. The piston rod is connected with the piston and moves in the axial direction of the trim cylinder following the movement of the piston. The support member is slidable relative to the piston rod and arranged to support the piston rod so that the piston rod's axial center can become tilted with respect to the axial center of the cylinder.
    Type: Grant

  • Method of making gear pump
    Patent number: 6996905
    Abstract: An improved high pressure intermeshing gear pump that achieves high efficiency and a low cost by forming the pumping cavity such that no fillets exist at the corners permitting closed fits without utilizing bearing end plates. In addition an improved coupling between the gears and their supporting shafts is disclosed as is a simplified machining method that eliminates burrs that may be formed during the drilling operations.
