Patent number: 7644727Abstract: A hydraulic fluid reservoir and hydraulic pump combination has at least one hydraulic fluid port and includes a container with a hollow body having a top and a conduit having a bottom within the container and a top above the bottom. The conduit has an opening adjacent to the bottom of the conduit. The opening is spaced apart below the top of the container. A closure member is releasably, sealingly connected to the top of the conduit. Hydraulic fluid can be added to the container via the conduit up to the level of the opening of the conduit. Addition of further hydraulic fluid fills the conduit to the top thereof and the conduit overflows if additional hydraulic fluid is added after the top of the conduit is reached by the fluid. Preferably the container has a main interior chamber and a smaller chamber which is adjacent to one of the side walls of the container. The smaller chamber is has a bottom opening near the bottom of the smaller chamber which communicates with the main interior chamber.Type: GrantFiled: June 20, 2007Date of Patent: January 12, 2010Assignee: Teleflex Canada Limited PartnershipInventors: Brian Dudra, Eric B.

Publication number: 20080078318Abstract: An apparatus and method for providing power assisted steering for a marine craft having a manually operable steering pump and a hydraulic steering actuator. A powered hydraulic pump is hydraulically connected between the manually operable pump and the actuator. Hydraulic fluid volume output of the steering pump and hydraulic fluid volume output of the powered pump are sensed. The fluid output of the steering pump is compared with the fluid output of the powered pump and the powered pump is operated so that the output of the powered pump is commensurate with output of the steering pump.Type: ApplicationFiled: October 31, 2007Publication date: April 3, 2008Inventors: Brian Dudra, Tat Lung Ray Wong, Neal Wesley Wood

Patent number: 7128626Abstract: There is provided a hydraulic steering assembly for applying a force to two or more marine propulsion units. Each propulsion unit has a steering axis and a tilt axis. The tilt axis is generally perpendicular to the steering axis thereof. Each propulsion unit is rotatable about the steering axis and is supported for arcuate movement about the tilt axis thereof. The steering assembly comprises a hydraulic steering actuator including a cylinder and an elongated piston rod. The cylinder has a first end and a second end. The elongated piston rod is reciprocatingly mounted within the cylinder and extends through the cylinder for movement along a piston rod axis. A pair of support arms are pivotable about the tilt axis of a first propulsion unit. The support arms are connected to the piston rod axis allowing arcuate movement of the piston rod about the tilt axis, while maintaining the piston rod axis parallel to the tilt axis.Type: GrantFiled: January 12, 2005Date of Patent: October 31, 2006Assignee: Teleflex Canada IncorporatedInventors: Brian Dudra, Leon Keng

Publication number: 20050287884Abstract: There is provided a hydraulic steering assembly for applying a force to a tiller of a marine, outboard propulsion unit and for rotating said propulsion unit about a steering axis between a center position and hard over positions to each side of the center position, the propulsion unit being supported for arcuate movement about a tilt axis which is generally perpendicular to the steering axis. The steering assembly comprises a hydraulic steering actuator including a cylinder and an elongated piston rod reciprocatingly mounted within the cylinder and extending through the cylinder for movement along a piston rod axis. The piston rod has opposite ends. A pair of support arms is pivotable about the tilt axis of said propulsion unit and is connected to the piston rod near the opposite ends thereof. The support arms allow arcuate movement of the rod about the tilt axis, maintaining the rod axis parallel to the tilt axis.Type: ApplicationFiled: June 29, 2004Publication date: December 29, 2005Inventor: Brian Dudra
