Title: Hydraulic selector valve
Inventor: HIRAKAWA SHIGEKI
IPC: F16H61/00
Filed: 2003-05-22
Abstract: <P>PROBLEM TO BE SOLVED: To provide a hydraulic selector valve of a hydraulic control device for an automatic transmission enabling a reduction in the deformation of a housing by reducing the bound of a spherical member.  <P>SOLUTION: A housing body 22 comprises a groove part 27 at a bottom wall part 22e forming a selection chamber 23. When a spherical member 30 closes the end part of a first passage 24 or a second passage 25, hydraulic pressure flowing in the selection chamber 23 not only flows into a third passage 26 but also flows into the rear part of the spherical member 30 via the groove part 27 formed in the housing body 22. Accordingly, there is almost no pressure difference of hydraulic pressure between the third passage 26 side and the anti-third passage side of the spherical member 30. As a result, since the bound of the spherical member 30 in the selection chamber 23 can be reduced, the deformation of a plate member 21 due to impact between the spherical member 30 and the housing body 22 can be reduced.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
