Control valve and hydraulic control device for continuously variable transmission devices |
摘要 |
A control valve is shown for a continuously variable transmission, with a spool of the control valve being maintained at a fixed transmission ratio position between an up-shift position and a downshift position when a signal pressure supplied to the control valve falls within a certain range. The signal pressure is provided to the control valve through a pressure line that is divided, with one branch of the signal pressure line being connected to a first input port of the control valve and the other branch being connected to a second input port through an orifice. Application of a signal pressure within a certain range results in the drain port being selectively connected with the second input port.
