摘要： A vibration damper assembly to absorb vibrations in a camshaft and sprocket system has a sprocket positioned around a camshaft, an inertia ring positioned around the camshaft and adjacent the sprocket, yet capable of moving independently of the sprocket, and a hub member positioned around the camshaft adjacent the inertia ring. Frictional material is interposed between the hub member and a rim portion of the inertia ring whereby the inertia ring and hub member slide with respect to one another along the frictional material to absorb vibrations from the camshaft through heat dissipation.

摘要： In a variable cam timing (VCT) system that has a crank shaft coupled to at least one cam shaft. The system has at least one timing gear associated with the crank shaft or a cam shaft. The timing gear includes at least two groups of toothlike projections including a first group having a first distance to the center of the wheel, and a second group having a second distance to the center of the wheel. The first distance is different from the second distance. Whereby torsional energy for torque actuated purposes is increased for the VCT system. The system may further include a resonator which is positioned upon the at least one cam shaft, the resonator including at least one mass and at least one elastic element. Whereby torsional oscillation of the at least one cam shaft at a predetermined engine speed range is increased.

摘要： A variable valve timing system includes a toothed rotating sleeve, a rack, and an actuator. The rack has a first end, a second end with a plurality of teeth in meshing contact with the teeth of rotating sleeves of the valve and being linearly moveable to rotate the sleeves. The actuator includes a housing, a control valve, and at least one check valve. The housing slidably receives a piston coupled to the rack separating a chamber in the housing into first and second chambers. The control valve selectively directs fluid from the first to the second chamber or vice versa. When the rack is shifted linearly by vibrational impulses from the engine, the piston moves linearly within the housing, pressurizing the first or the second chamber and under control of the control valve, fluid recirculates from the first or the second chamber to the other chamber.

摘要： A variable cam timing control module for an internal combustion engine having at least one cam position sensor, at least one solenoid to actuate a cam phasing device, a driven outer cam sprocket position sensor and a microcontroller. The microcontroller may receive a set point angle signal from the engine's Electronic Control Unit, which it compares with input signals from the driven outer cam sprocket position sensor and the at least one cam position sensor to determine the proper cam phase angle. The microcontroller then sends a signal to the at least one solenoid to adjust the corresponding cam phasing device so that the cam phase angle matches the commanded set point.

摘要： An electromagnetic valve actuator system for controlling the operation of a valve in an internal combustion engine comprising a valve having a valve stem with a valve head at one end. The valve is reciprocable along the longitudinal central axis of the valve stem to alternatingly move the valve head between a first position and a second position. A first coil is positioned on a first laminated core having a gap and a thickness. A second coil is positioned on a second laminated core having a gap and a thickness. The gaps of the first and second cores are aligned. An armature on the valve stem passes through the gaps of the first and second laminated cores, such that when the armature is centered in either of the gaps at least a portion of the armature extends slightly passed the thickness of the other laminated core.
