    摘要: A remotely mounted 4-way valve (2) or two solenoid valves (12) (13) control a center mounted spool valve (28). In the 4-way valve embodiment, one control port (3) provides oil pressure to one end (26) of the spool valve (28) and the other control port (4) provides oil pressure to the other end (27) of the spool (25). In the embodiment with two solenoid valves, one solenoid valve control port (16) feeds oil to one end (26) of the spool (25) and another solenoid valve control port (17) feeds oil to the other end (27). For both of these control systems, the relationship of percent of control signal to percent of control pressure is mapped into the controller, and varies as the engine oil pressure and temperature changes. In a preferred embodiment, a position sensor (34) mounted to the spool valve position reduces this error by having a control loop controlling the position of the spool valve. There is also another loop to control the phaser angle.

    摘要: The chain tensioner includes a tensioner arm with a blade spring and a wedge-shaped piston. Complementary friction surfaces of a pair of pawls push against the wedge-shaped piston to dampen the motion of the blade tensioner and hence tension the chain. The pawls are urged together and against the piston by spring loading. The combination of a blade tensioner and a wedging feature provides better chain control than a blade tensioner alone. The system requires no hydraulic fluid pressure from the engine.

    摘要: A tensioner including a housing, a piston, a piston spring, a first pawl and a second pawl. The housing has a bore for slidably receiving a piston. The piston has a plurality of teeth formed along at least a portion of the outer circumference of the piston. The piston spring biases the piston in an outward direction from the bore. The first and second pawls are pivotally attached by a pin and received by grooves in the housing. The pawls are biased toward the teeth of the piston by first and second springs. The pawls are preferably adjacent to each other or 180 degrees apart. The first pawl is preferably half a pitch ahead of the second pawl, such that when the second pawl ratchets a tooth on the piston, the first pawl is sliding along the ramp toward the next tooth.

    摘要: A variable camshaft timing system having a camshaft with a vane-type rotor, where oscillation of the housing relative to the vane is actuated by pressurized engine oil, derived in part from a torque pulse in the camshaft. An annular locking plate is positioned coaxially with the camshaft and the housing. It is moveable relative to the housing along the longitudinal central axis of the camshaft between two positions, the teeth on the locking plate engaging the teeth on the housing and where the teeth on the locking plate are disengaged from the teeth on the housing, each position preventing circumferential movement of the housing relative to the rotor. The locking plate is biased by a plurality of metallic straps towards engagement of the teeth on locking plate with the teeth on the housing. The straps have one end secured to the locking plate and another end secured to the rotor.

    摘要: The cam phaser of the present invention includes an externally mounted DPCS (234) with spool position feedback to control the position of a center mounted spool valve (192) and control the phase angle of the cam mounted phaser. A position sensor (300) is mounted to the spool valve position such that a control loop (400) controls the position of the spool valve (192). A second, outer loop (430) controls the phaser angle. An offset is preferably added to the spool valve position to move the spool valve to its steady state or null position. This null position is required so that the spool (200) can move in to move the phaser in one direction and outward to move the phaser in the other direction. This type of system reduces any frictional or magnetic hysteresis in the system.

    摘要: In a boat that was not designed for or required a live well, a built-in tank, for the holding of newly caught fish, a portable tank will serve as a live well that will hold fish that are caught and a bait well that would receive minnows or leaches. An electric pump powered by a battery of the boat or portable battery pumps water from the lake into the tank to fill, aerate and circulate the water in the tank. An electric pump powered by a battery of the boat or portable battery pumps water out of the tank and provides for overflow. A series of three valves control the water intake, water overflow and re-circulation of water in the tank. These operations are controlled by the open or closed combinations of the three valves. The majority of the live well is to receive newly caught fish with the smaller portion of the live well to serve as the holder for live bait. Aerated water filters throughout the entire live well.

    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.
