Patent number: 9388804Abstract: An oil pressure relief valve for use in the oil pump lubrication system of an internal combustion engine is controlled by both oil pump outlet pressure and by pilot pressure from a pilot valve which is selectively applied by a control member, preferably a two-way valve that is operated by the engine control module. The pilot valve selectively supplies one of the oil pump outlet pressure or the engine gallery pressure to the control member which selectively supplies pilot valve pressure to the oil pump pressure relief valve which has a single piston. The pilot valve includes first and second pistons for selectively controlling back pressure from the pressure relief valve and for managing changes in oil pressure due to changes in the engine gallery to maintain a virtually constant pressure even as oil pump speed increases when the control member connects the pilot valve to the pressure relief valve resulting in a fuel economy benefit and improved control of the oil pump pressure.Type: GrantFiled: January 27, 2012Date of Patent: July 12, 2016Assignee: Magna Powertrain Inc.Inventors: Matthew Williamson, Ken T.

Patent number: 6756892Abstract: A monitoring system for monitoring pressure in a tire of a trailer includes an active sensor, a receiver and an indicator. The active sensor is positioned at a first location and is operable to sense the pressure. The receiver is positioned at a second location remote from the first location and within proximity to the sensor. The receiver is operable to generate a signal indicative of the pressure and includes an inductor, and an amplifier having a feedback path. The inductor is positioned relative to the receiver to create an electromagnetically coupling between the inductors such that feedback from the coupling is one of either a substantially zero feedback and a negative feedback.
