A variable cam timing phaser for an internal combustion engine including a piloted valve in the rotor assembly, movable from a first position to a second position, and detent lines communicating with the advance chamber or the retard chamber are restricted and or blocked when the rotor assembly is in or near an intermediate phase angle position. When the piloted valve is in the first position, fluid is blocked from flowing through the piloted valve. When the piloted valve is in a second position, fluid is allowed to flow between the detent line from the advance chamber and the detent line from the retard chamber through the piloted valve and a common line, such that the rotor assembly is moved to and held in the intermediate phase angle position relative to the housing assembly.

123 9015, 123 9017, 123 9027, 123 9031, 74724, 464160

A phaser for adjusting the timing between a camshaft and a crankshaft. The phaser consists of an outer housing having internal and external teeth and an inner housing connected to the camshaft. The outer teeth couple to the cam drive—the timing chain, timing belt or timing gears. A worm mounted on the inner housing is meshed with the internal teeth of the outer housing. The worm gear is connected to one or two drive wheels, which are rotated by contact with stationary plates. The plates are moved by electromagnetic coils to contact the drive wheel or wheels, and turn them in one direction or the other. The actuators are activated by an engine control unit. The plates can be mounted concentrically on one side of the phaser, or on opposite sides.

A variable cam timing system that utilizes the same spool that controls the VCT mechanism to actively control the locking pin. The positions of the spools multiple lands directly influences whether source oil is supplied to both the locking pin and either the retard or advance chamber of the phaser.

A hydraulic tensioner includes a piston that is pivotally mounted to a tensioner arm. The piston is slidably received within a hollow body that is pivotally mounted to a mounting block or engine. In different embodiments, the body is mounted to the tensioner arm while the piston is biased against the mounting block or pivotally connected to the mounting block or engine.

An actuator for varying a compression ratio of an engine by varying by the rotary motion of a control shaft coupled to a variable compression ratio device. The actuator comprising: a housing assembly mounted to the engine; a rotor assembly coupled to the control shaft defining at least one vane separating a chamber in the housing assembly into a first chamber and a second chamber, the vane being capable of rotation to shift the relative angular position of the rotor assembly from a first rotational position associated with a first compression ratio to a second rotational position associated with a second compression ratio; and a control valve moveable to a first position in which torsional energy from the control shaft is permitted to rotate the rotor assembly in a direction from the first rotational position toward the second rotational position and to a second position opposite the first position.

123 9017

A variable cam timing phaser with a control valve for directing fluid from a fluid input to and from the advance chamber and the retard chamber of the phaser through an advance line, a retard line, a common line, an advance default line, a retard default line, and at least one exhaust line. The control valve being movable between a default mode and an oil pressure actuated mode. In the default mode, the control valve blocks exhaust lines, retaining fluid within the chambers. The oil pressure actuated mode includes at least an advance mode, a retard mode, and a holding position.

An internal combustion engine in which the variable cam timing controls for a variable cam timing mechanism include a variable force solenoid mounted within a hollow portion of the camshaft. The variable force solenoid is maintained in place within the hollow camshaft by a tubular shaft fixed to the engine and a bearing between the solenoid and the variable cam timing mechanism.

A hydraulic tensioner having a plunger slidably fitted in a cavity in a housing and biased in a protruding direction by a spring and fluid. A check valve permits fluid to only flow into, and thereby protrude the plunger, but not out of the cavity. A pressure relief valve is mounted on the housing and is in communication with the cavity. The relief valve includes a flat spring member applying a preload against a reed valve to seal an exhaust passageway connecting to the cavity.

A variable camshaft timing mechanisms having a vane/housing format is provided. Working hydraulic chambers are created by imposing either single or multiple vanes of a rotor attached to the camshaft into a cavity in a housing that is attached to the camshaft sprocket. Fluid is allowed to normally exhaust from the hydraulic chamber during normal phasing until the rotor nears the end of its travel.

A VCT phaser for an engine having a housing, rotor and a spool valve. The rotor having a bore comprising an open outer end, an inner surface, and inner end having a vent port and arranged along the bore, an advance port, a common port, a retard port, and a lock port. The spool valve comprises a spool with a first land, a first groove, a second land, a second groove, and a third land, with the area between the inner surface of the bore and the first groove defining a first chamber, the area between the bore and the second groove defining a second chamber, and the area between the bore and the inner end of the spool defining a third chamber. A passage between the first groove and the second groove for fluid passage provides fluid communication between the first chamber and the second chamber and lock pin.
