摘要： A hydraulic control valve has a solenoid body, a selectively energizable coil, and an armature positioned adjacent the coil. The coil is energizable to generate a magnetic force that moves the armature from a first position to a second position. A pole piece is positioned to establish a gap between the pole piece and the armature. The pole piece has a cavity that opens at the gap. A piston extends from the armature into the cavity and moves with the armature. The armature is biased to seat at a valve seat in the first position by pressurized fluid. Magnetic force required to move the armature away from the valve seat is a function of the difference between an area of the piston and an area defined by contact of the armature at the valve seat.

摘要： A fluid level detection system (10; 110; 210; 310; 410) includes a fluid reservoir (15; 15A, 15B, 15C; 15D; 15E, 15F, 15G, 15H; 115) defining a cavity (60; 160) for holding fluid therein. A fluid level sensor (12; 12A, 12B, 12C; 12D, 12E, 12F; 12G, 12H, 12I, 12J; 112) is mounted to the fluid reservoir. The solenoid body (20; 120) defines a first opening (62; 162) establishing fluid communication between an armature chamber (42; 142) and the cavity defined by the reservoir. Travel time of an armature (44; 144) within the armature chamber is thereby affected by fluid level in the reservoir. A controller (16; 16A; 16B; 116; 416) is operatively connected to the sensor and is operable to receive a sensor signal (17; 17A, 17B, 17C; 17D, 17E, 17F; 17G, 17H, 17I, 17J) indicative of travel time from the sensor and formulate a control signal (21; 21 A; 21B; 421) corresponding thereto. A power source (38; 38A; 38B; 138; 438) is operatively connected to the controller for energizing the coil and the controller. In some embodiments, multiple fluid containing components (15A, 15B, 15C; 15E, 15F, 15G, 15H) are connected with one or more controllers (16A; 416; 423). An engine (15E), a transmission (15F), and rear axle differentials (15G, 15H) on a vehicle may be equipped with sensors (12G, 12H, 12I, 12J) to provide fluid level, temperature and viscosity information.

摘要： A fluid condition and level sensor (12, 112) is provided that includes a solenoid body (20, 120), a coil (30, 130), and an armature (44, 144) surrounded by the coil. The solenoid body defines an armature chamber (42, 142) in which the armature is movable in response to energizing of the coil. The sensor is mounted to a reservoir (15, 115) such that a first portion (24, 124) of the solenoid body extends into a cavity (60, 160) defined by the reservoir, and so that movement of the armature is substantially transverse to a direction of fluid level change in the reservoir. The first portion of the solenoid body defines an opening (62, 162) permitting fluid communication between the cavity and the armature chamber, such that fluid enters and is displaced from the armature chamber through the opening as the armature moves, movement of the armature within the armature chamber thereby being affected by fluid level in the reservoir.

摘要： A method for monitoring operation of a solenoid valve having an armature and a poppet coupled to the armature includes the steps of energizing a coil in the valve to generate a current signature reflecting current vs. time, detecting a first inflection point in the current signature, wherein the first inflection point occurs when the armature starts to move from one of the open and closed positions toward the other of the open and closed positions, and detecting a second inflection point in the current signature. The second inflection point occurs when the armature moves completely to the other of the open and closed positions. In one embodiment, the first inflection point indicates when the valve begins to open, making it possible to accurately determine the elapsed opening time of the valve.
