Patent number: 8612072Abstract: The system herein disclosed automatically detects whether an engine control unit instance number of a multi-engine marine vessel needs changing. Each engine control unit is electronically paired with a respective servo controller. A vessel controller is in communication with the servo controllers. The vessel controller commands in turn each servo controller to switch on its paired engine control unit, read the instance number of its paired engine control unit, switch off its paired engine control unit, and convey the instance number back to the vessel controller. The vessel controller then compares the instance numbers of the engine control units. If at least two instance numbers of the engine control units are duplicates of each other, the vessel controller ascertains that at least one of the instance numbers of the engine control units needs to be changed and assigns a new instance number to one of the engine control units.Type: GrantFiled: February 11, 2010Date of Patent: December 17, 2013Assignee: Teleflex Canada, Inc.Inventors: Pierre Garon, Neil Garfield Allyn, James Steven Monczynski, Thomas Samuel Martin

Patent number: 7806142Abstract: A combination check valve and relief valve has a valve body with an inlet, an outlet, and a valve chamber operatively interposed between the inlet and outlet. A check valve may be integrated with the relief valve and therefore simplify a hydraulic system. The valve includes a relief valve member which is within the valve chamber. The valve also includes a resilient member with a first end and a second end. The first end of the resilient member operatively engages the relief valve member. The valve includes a setting member pressure-fit within the valve chamber to operatively engage the second end of the resilient member. The resilient member is resiliently biased between the setting member and the relief valve member to bias the relief valve member against a relief valve seat, whereby, when pressurized fluid communicates with the inlet, the resilient member is compressed, and the relief valve member disengages its seat to enable the fluid to pass through to the outlet.Type: GrantFiled: June 27, 2007Date of Patent: October 5, 2010Assignee: Teleflex Canada Inc.Inventors: Davor Baros, Mark Ellens
