Publication number: 20160097406Abstract: Hydraulic bump stops and bi-directional diverter valves may be used to protect hydraulic systems, including, for example in one embodiment, the hydraulic actuators of an active suspension system, from damage due to operation outside the normal operating range of the system. In some embodiments, a hydraulic bump stop may be used to slow down the motion of a piston at the extremes of the compression and/or extension strokes of an actuator. In another embodiment, a diverter valve may be used to protect a hydraulic motor/pump in a hydraulic system from an over-speed condition. When the piston in an active suspension system actuator moves at a speed in excess of a threshold value, one or more diverter valves may be used to divert flow away from the hydraulic motor/pump. In some embodiments, a diverter valve may be a dual or single spool bi-directional diverter valve.Type: ApplicationFiled: October 6, 2015Publication date: April 7, 2016Applicant: Levant Power CorporationInventors: Richard Anthony Zuckerman, Clive Tucker, Colin Patrick O'Shea, Jack A.

Publication number: 20160075205Abstract: A method of on-demand energy delivery to an active suspension system is disclosed. The suspension system includes an actuator body, a hydraulic pump, an electric motor, a plurality of sensors, an energy storage facility, and a controller. The method includes disposing an active suspension system in a vehicle between a wheel mount and a vehicle body, detecting a wheel event requiring control of the active suspension; and sourcing energy from the energy storage facility and delivering it to the electric motor in response to the wheel event.Type: ApplicationFiled: September 21, 2015Publication date: March 17, 2016Applicant: Levant Power CorporationInventors: Zackary Martin Anderson, Marco Giovanardi, Clive Tucker, Jonathan R.

Publication number: 20160031285Abstract: A multi-path fluid flow control valve for a shock absorber that restricts fluid into a first path while opening fluid flow to a second path when a given fluid flow velocity is reached. Exemplary configurations of this diverter valve are disclosed such as a spring loaded disc valve with face sealing lands, and a spool valve with diametric sealing lands. Applications include active suspension dampers in order to limit maximum RPM into a hydraulic motor. For such a system, in one mode the diverter valve allows fluid to move unrestricted into the hydraulic motor. When fluid velocity reaches a tunable set point, in a second mode the diverter valve restricts flow into the hydraulic motor and bypasses it shuttling fluid into the opposite side of the damper. In some cases progressive damping valves are utilized in series or parallel to smooth damping characteristics during, before, and after transitions.Type: ApplicationFiled: March 14, 2014Publication date: February 4, 2016Inventors: Clive Tucker, Johannes Schneider, Colin Patrick O'Shea, Marco Giovanardi, Richard Anthony Zuckerman, Patrick W.

Publication number: 20140294601Abstract: Hydraulic pumps/motors are used to convert between rotational motion/power and fluid motion/power. Pressure differential is achieved across the pump/motor by applying torque to either aid or impede rotation which generally results in either a pressure rise or pressure drop respectively across the unit. This torque is often supplied by an electric motor/generator. Especially in positive displacement pumps/motors this pressure differential is not a smooth value but rather it contains high frequency fluctuations known as pressure ripple that are largely undesirable. With thorough analysis it can be discovered that these fluctuations occur in a predictable manner with respect to the position (angular or linear) of the pump/motor. Using a model that contains this information, a feed-forward method of high-frequency motor torque control is implemented directly on the hydraulic pump/motor by adding to the nominal torque, a model-based torque signal that is linked to rotor position.Type: ApplicationFiled: April 1, 2014Publication date: October 2, 2014Applicant: Levant Power CorporationInventors: Colin Patrick O'Shea, Tyson David Sawyer, Marco Giovanardi

Publication number: 20140294625Abstract: A method and system for measuring rotor position or velocity in an electric motor disposed in hydraulic fluid. The system comprises a contactless position sensor that measures electric motor rotor via magnetic, optical, or other means through a diaphragm that is permeable to the sensing means but impervious to the hydraulic fluid. An electronic sensor is positioned outside the operating fluid, whereas the motor is located in the fluid volume.Type: ApplicationFiled: April 1, 2014Publication date: October 2, 2014Applicant: Levant Power CorporationInventors: Clive Tucker, Vladimir Gorelik, Jonathan R.

Patent number: 7694943Abstract: A carburetor for feeding separate lean and rich channels of an engine intake duct includes a body having a mixing passage with an air intake side and an engine outlet side. A throttle shutter is rotatable about an axis transverse the mixing passage, and a partition is located within the mixing passage upstream of the throttle shutter. The downstream edge of the partition is adjacent the throttle shutter axis whereby in use of the carburetor the partition defines an extension of the lean and rich channels upstream of the throttle shutter, the partition thus providing substantial isolation between the lean and rich channels for all rotational positions of the throttle shutter. In a preferred embodiment a choke shutter is located upstream of the throttle shutter and is rotatable about a further axis transverse the mixing passage, the upstream edge of the partition being adjacent to the axis of the choke shutter.Type: GrantFiled: May 4, 2007Date of Patent: April 13, 2010Assignee: Barcarole LimitedInventors: John Mason, Roger Bowles, Patrick O'Shea
