INTERMEDIATE PHASE ADJUSTMENT APPARATUS OF CVVT |
| 摘要 |
An intermediate phase adjustment apparatus of a CVVT includes check valves provided to prevent backflow of oil when the oil moves from one chamber to another chamber in order to secure a parking position of a lock pin in a CVVT of which an advance chamber and a retard chamber are formed between a rotor and a stator, and an oil inlet portion formed at the stator to correspond to inlet portions of the check valves, wherein an oil inlet portion provided at one chamber is formed larger than an oil inlet portion provided at the other chamber by a predetermined size, and the open angles of the check valves for making oil to flow into a chamber are increased, thereby preventing an offset occurrence by a cam torque. |
