    Abstract: A hydraulic tensioner for a wrapped power transmission device designed to minimize the amount of air present in the pressure chamber. The hydraulic tensioner includes a combination pressure relief-check valve for use with a hollow piston pressure chamber containing a spring within the pressure chamber to bias the piston outward from the bore. The valve housing is designed to reduce the volume of fluid contained within the pressure chamber minimizing the amount of air which may become trapped in the pressure chamber thus improving the performance of the tensioner.

    Abstract: A hydraulic tensioner is provided with a plunger slidably fitted in a cavity in the tensioner housing and biased in a protruding direction by a spring and fluid. An integral inlet check and pressure relief valve is positioned in the cavity and permits fluid to only flow into the cavity and thereby protrude the plunger but not out of the cavity until a high pressure condition is reached whereupon fluid is relieved out of the cavity back to the fluid source. The integral inlet check and pressure relief valve includes a check spring biasing a valve member a against a pressure relief disk that is biased against the valve member by a pressure relief spring.

    Abstract: A transmission for an engine or motor with a reduced package size and increased efficiency comprising: an input sprocket, an output sprocket, a chain, and a planetary gear set. The output sprocket is drivingly connecting to the input sprocket through the chain. The output sprocket has a hollow center portion that receives the sun gear of the planetary gear set. The planetary gear set also includes at least two planet gears meshed with the sun gear which are mounted to a fixed planet carrier for driving a differential with a ring gear portion. When the input sprocket is rotated in a first direction, the chain drives the output sprocket and the sun gear in the first direction, and the sun gear drives the planet gears to rotate in a second direction, opposite the first direction, driving the ring gear portion and differential in the second direction.

    Abstract: An internal combustion engine having a camshaft (14) and variable camshaft timing system, where a rotor (22) is secured to the camshaft (14) and is rotatable but non-oscillatable with respect to the camshaft (14). A housing (68) circumscribes the rotor (22), is rotatable with both the rotor (22) and the camshaft (14), and is further oscillatable with respect to both the rotor (22) and the camshaft (14) between a fully retarded position and a fully advanced position. A locking configuration prevents relative motion between the rotor and the housing (68), and is mounted within either the rotor (22) or the housing (68), and is respectively and releasably engageable with the other of either the rotor (22) and the housing (68) in the fully retarded position, the fully advanced position, and in positions therebetween. The locking device includes a locking piston (42) having keys (46) terminating one end (44) thereof, and serrations (60) mounted opposite the keys (46) on the locking piston (42) for interlocking the rotor (22) to the housing (68). A controlling configuration controls oscillation of the rotor (22) relative to the housing (68).

    Abstract: An internal combustion engine includes a camshaft (40) and hub (30) secured to the camshaft (40) for rotation therewith, where a housing (20) circumscribes the hub (30) and is rotatable with the hub (30) and the camshaft (40), and is further oscillatable with respect to the hub (30) and camshaft (40). Driving vanes (22) are radially inwardly disposed in the housing (20) and cooperate with the hub (30), while driven vanes (32) are radially outwardly disposed in the hub (30) to cooperate with the housing (20) and also circumferentially alternate with the driving vanes (22) to define circumferentially alternating advance and retard chambers (28A/28R). A configuration for controlling the oscillation of the housing (20)relative to the hub (30) includes an electronic engine control unit (70), and an advancing control valve (50) that is responsive to the electronic engine control unit (70)and that regulates engine oil pressure to and from the advance chambers(28A). A retarding control valve (60) responsive to the electronic engine control unit (70) regulates engine oil pressure to and from the retard chambers (28R). An advancing passage (44) communicates engine oil pressure between the advancing control valve (50) and the advance chambers (28A), while a retarding passage (46) communicates engine oil pressure between the retarding control valve (60) and the retard chambers(28R).

    Abstract: A hydraulic tensioner includes a plastic cap vent or check valve at the top of the piston. Oil and air that pass through the top end of the piston accumulate in the space between the plastic cap and the piston. The plastic cap moves small distances in the axial direction to permit the escape of air and oil through the plastic cap to atmosphere. A low rate spring may be used to cause the plastic cap to move away from the piston.
