摘要： A variable cam timing phaser for an internal combustion engine includes a housing (10) and a rotor (20) connected coaxially with respect to a camshaft for rotation relative to one another. The housing (10) and the rotor (20) can define at least one cavity (10a) with a vane (22) dividing each cavity (10a) into a first chamber (16) and a second chamber (18). A control valve (24) can have a longitudinally reciprocal spool (36). The spool (36) can move between an advance timing position and a retard timing position within a Cam Torque Actuated mode of operation, an advance timing position within a Torsional Assist mode of operation, and at least one null position. The spool (36) can connect the first chamber (16), the second chamber (18), a check valve (40) and an actuating fluid supply source (46) with respect to one another, and can connect a passage (62) associated with a lock pin (60) between an exhaust vent (48a, 48b) and the actuating fluid supply source (46).

摘要： A variable cam timing phaser for an internal combustion engine having a concentric camshaft can include a stator (14) having an axis of rotation. An outer rotor (20) can rotate independently relative to the axis of rotation of the stator (14). A combination of an outer vane (22) and cavity (20a) can be associated with the outer rotor (20) to define first and second outer variable volume working chambers (20b, 20c). A radially inner located rotor (30) can rotate relative to the axis of rotation and independently of both the stator (14) and the outer rotor (20). A combination of an inner vane (32) and a cavity (30a) can be associated with the inner rotor (20) to define first and second inner variable volume working chambers (30b, 30c). When the first and second, outer and inner chambers (20b, 30b, 20c, 30c) selectively communicate with a source of pressurized fluid, phase orientation of the outer and inner rotors (20, 30) with respect to one another and with respect to the stator (14) is facilitated.

摘要： A phaser for maintaining an angular relationship between a crank shaft and a cam shaft or among more than one cam shafts is provided. The phaser includes a rotor having a plurality of vanes integral to the rotor and protruding from the rotor body. The plurality of vanes is disposed to oscillate within their respective chambers formed by the rotor and a housing, thereby maintaining the angular relationship. The phaser also includes a shoulder integral to the rotor and interposed between one of the pluralities of vanes and the rotor body, thereby ensuring that the rotor face is always covering a locking pin hole regardless of vane position. The phaser further includes an inlet check valve located within the phaser structure or in very close proximity to the phaser, thereby reducing control fluid leakage.

摘要： A closed loop chain tensioner system having a drive sprocket, one or more driven sprockets, a first mechanical tensioner located adjacent a slack strand and a second mechanical tensioner located adjacent a tight strand. Each tensioner is independently pivotally mounted to the engine block. The mounting point may be located at any point along the length of each tensioner. The tensioners are then linked to each other by a rigid, solid link. This solid link enables the tensioners to act in unison, thus providing damping across both strands of chain in response to engine torsional variations.

摘要： A tensioner for imparting tension to a chain in a closed loop chain drive system of an internal combustion engine is disclosed. The tensioner contains two tensioning devices, one for each strand of chain that traverses between a drive sprocket and at least one driven sprocket. The two tensioning devices are installed on a single bracket which is mounted to the engine housing at a single dampened pivot mount. The pivot mount is positioned equidistant from the mid points along the lengths of each of the chain sliding surfaces of each of the tensioning devices to substantially form an isosceles triangle.

摘要： A variable cam timing assembly (10) and method for an internal combustion engine of a motor vehicle includes a cam phaser (22) connected between an inner camshaft (12a) and an outer camshaft (12b) of a concentric camshaft (12). A torsional drive mechanism (14) connects between the cam phaser (22) and the inner camshaft (12a) for transmitting rotational torque. The torsional drive mechanism (14) permits adjustment for perpendicularity and axial misalignment of the inner and outer camshafts (12a, 12b), while maintaining a torsionally stiff coupling between the cam phaser (22) and one of the inner and outer camshafts (12a, 12b) of the concentric camshaft (12). The torsional drive mechanism (14) can be formed from one of a flexible shaft coupling (40), a transversely split driven gear (140), a transversely split sprocket ring gear (240), a transverse face spline gear (340), and a pin and slot combination drive (440).
