摘要： A hydraulic controller comprises a structure composed of a separator plate 70 sandwiched between first and second valve bodies 60a and 80a, in which structure, an oil passage 103 connecting a SC shift valve 92 provided upstream and a SC backup valve 94 provided downstream is provided with a choke 75. When the separator plate 70, in which a choke opening 75a is formed, is sandwiched between the first and second valve bodies, the upstream part of the oil passage 103 is in fluid communication with one end of the choke opening 75a while the downstream part of the oil passage 103 is in fluid communication with the other end of the choke opening 75a. In this arrangement, a long narrow room formed by the choke opening 75a sandwiched between the first and second valve bodies comprises the choke 75.
摘要翻译：液压控制器包括由夹在第一和第二阀体60a和80a之间的隔板70构成的结构，其中连接设置在上游的SC换档阀92的油通道103和设置在下游的SC支撑阀94设置有扼流圈75.当形成有阻塞开口75a的隔板70夹在第一和第二阀体之间时，油路103的上游部分与阻塞开口75a的一端流体连通，同时油路103的下游部与阻塞开口75a的另一端流体连通。在这种布置中，由夹在第一和第二阀体之间的扼流开口75a形成的长狭窄的房间包括扼流圈75。

摘要： A stepped down groove 53 is provided around the peripheral surface of a rod portion 43 of a spool 40 which faces a third oil groove 33. Both the axial ends 53a and 53b of the stepped down groove 53 are located axially outside of both the axial ends 33a and 33b of the third oil groove 33 at least while the valve is in pressure-adjusting condition. Also, another stepped down groove 52 is provided around a land 42 which faces a first oil groove 31. Both the axial ends 52a and 52b of the stepped down groove 52 come, respectively, to the right and left sides of the axial end 31b of the first oil groove 31 to which end the spool 40 shifts to increase the opening of the oil groove at least while the valve is in pressure-adjusting condition.
摘要翻译：在与第三油槽33相对的卷轴40的杆部43的周面的周面的周围设置有下降槽53。至少在阀处于压力调节状态时，阶梯式凹槽53的轴向端部53a和53b均位于第三油槽33的轴向端部33a和33b的轴向外侧。另外，在与第一油槽31相对的台肩42的周围设置有另一个下降槽52。阶梯式下陷槽52的轴向端部52a和52b分别到达第一油槽31的轴向端部31b的左右两侧，在该端部的第一油槽31的端部转动，从而增大开度至少在阀门处于压力调节状态时油槽。
