摘要： 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).

摘要： A variable valve timing control device includes a valve unit including a spool having a plurality of land portions at an outer circumference of the spool, and being formed with a drain flow path inside the spool. The valve unit allows a second pump port and a lock port to communicate with each other in a case where the spool is set at an unlock position where a lock state of a lock mechanism is released, and the valve unit closes the second pump port with the land portion of the spool and allows the lock port to communicate with the drain flow path in a case where the spool is set at a lock position where the lock mechanism is allowed to be shifted in the lock state.

摘要： A method of controlling a lock pin of a CVVT (continuous variable valve timing) system is provided. The method includes an oil supply operation of operating a spool of a valve bolt by means of oil drawn into the CVVT system and supplying the oil to the lock pin and a switching valve. The method further includes a switching-valve opening operation of opening the switching valve by means of pressure of the oil supplied in the oil supply operation, and a lock-pin releasing operation of supplying oil to a chamber when the switching valve opens and releasing the lock-pin when there is no difference in oil pressure between an advanced chamber and a retracted chamber.

摘要： A variable valve timing control device has, as control modes for adjusting inflow and outflow of oil with an OCV, a lock mode for moving a lock pin in a locking direction, a phase control mode for controlling a camshaft phase by a target phase in accordance with an operation state of an engine, and an oil filling mode for filling an advancement chamber and a retardation chamber with the oil in a state that the lock pin moves in the locking direction, before shifting from the lock mode to the phase control mode. When the oil filling mode has been selected, a target position of a spool is set based on viscosity of the oil, and the position of the spool is controlled so as to be the set target position.

摘要： The present disclosure provides a hydraulic control valve for a valve timing adjusting device of an engine. The valve timing adjusting device has a hydraulic control valve; a housing; a rotor installed in the housing and having vanes forming advance, retard and locking chambers, respectively; and a locking pin member elastically installed at the locking chamber. In particular, the hydraulic control valve includes: a valve body connected to the camshaft and having ports and a spool space; an outer spool elastically installed in the spool space and having distribution ports selectively communicated with or disconnected to the ports of the valve body; and an inner spool that is integrally coupled to the outer spool and forms a supply passage connected to a working fluid pump and a drain passage connected to a drain tank together. With this arrangement, the hydraulic control valve reliably provides phase angle control operation and the self-locking operation to adjust a valve timing and thereby improving engine performance

摘要： The invention relates to a camshaft adjustment device for an internal combustion engine, having a chamber housing, an actuating rotor which is received in the chamber housing and which can be pivoted about an axis which is concentric with respect to the circumferential axis of the chamber housing, wherein the actuating rotor has a plurality of dividing flanks which rise up radially over a cylindrical base surface of the actuating rotor, and in each case divide pressure chambers which are formed in the chamber housing into a first chamber section and a second chamber section. Sealing strips are inserted into the actuating rotor. The sealing strips form a fluid passage path. The latter can be blocked via a check valve device in such a way that the fluid passage is possible only in one direction.
