<p>A manual valve of a hydraulic control system for continuously variable transmission is provided to reduce a shift chock in a manual shifting process by controlling control pressure of a pressure control valve. A manual valve of a hydraulic control system for continuously variable transmission includes a valve body and a valve spool(50). The valve body includes one input port(60) and two output ports. The valve spool includes a first and second lands(54,56) for connecting selectively the input port with one of the output ports and shielding simultaneously the input port from the output ports. Slots(70,72) are formed at outer circumferences of both ends of the first and second lands. An inner end of each of the slots is connected to each of the output ports in a neutral state.</p> |
