に接続したことを特徴とする液圧無段変速装置。 A valve device V is interposed in the hydraulic fluid flow path between the hydraulic pump 50 and the hydraulic motor 51, and the valve device V has a partition wall 63 in the center of the interior, and an opening 62 formed in the interior and side wall is connected to the high pressure side. Valve box 61 divided into low pressure side and low pressure side
A partition wall 78 is provided at the center of the inside of the opening 62 to separate the inside and the opening into a left ventricular side and a right ventricular side. The rotary valve body 71 is brought into close and rotatable sliding contact.
The rotation of the valve body 61 makes it possible to change the cross-sectional area of the flow path that communicates between the high and low pressure sides of the valve body 61 and the left and right ventricular sides of the rotary valve body 71. On the discharge side of the pump 50, the low pressure side is connected to the hydraulic pump 5.
0, and the left and right chamber sides of the rotary valve body are connected to the hydraulic oil inlet and outlet ports 53 and 54 of the hydraulic motor 51, respectively.
A hydraulic continuously variable transmission characterized by being connected to.
