HYDRAULIC CONTROL VALVE
Document Type and Number:
Japanese Patent JP2011149499
Kind Code:
A
Abstract:

To secure, in a hydraulic control valve configured to selectively supply pressure-adjusted hydraulic oil to a destination according to a shift range, sufficient fail toughness with a simple structure reduced in the number of part items by sharing of a device.

The hydraulic control valve 1 includes a spool 20, a cylindrical sleeve 30 slidably receiving the spool 20, mechanical mechanisms 51, 55 for changing the rotating angle of the sleeve 30 according to the shift range, and a valve body 40 rotatably supporting the sleeve 30. An output port 34 provided in the sleeve 30 selectively communicates with any one of output oil passages 44a-44c provided in the valve body 40 according to the rotating angle of the sleeve 30, whereby the hydraulic oil adjusted in pressure by the spool 20 is delivered to the any one of the output oil passages 44a-44c and supplied to any one of hydraulic operating portions 72a-72c corresponding to the shift range, which is connected ahead.
