２．Ｌにシフトされている時と較べ、入力路と出力路と
の間隙が著しく大きくなっている。However, conventionally, while the shift lever of an automatic transmission is shifted to the drive (D) position, second (2) position, low 0 position, etc. and the rotating shaft 1 is being driven, the valve body 3 is closed as shown in FIG. The outer peripheral side large diameter portion 33 of the step 31 and the governor body inner wall 2
The governor pressure is adjusted by increasing or decreasing the size of the part B and the opening area of the oil drain port 25, but when the shift lever is in the old parking position, the governor pressure is below it. and the shift lever is in neutral (N),
When the vehicle is driven in the reverse (R) position, or when the rotary shaft 1 is stopped and the governor valve is located below it, the large diameter portion 33 does not overlap the inner wall 24, and the above-mentioned
2. The gap between the input path and the output path is significantly larger than when it is shifted to L.

となった。Therefore, if there is a large solid object such as a manufacturing chip in the hydraulic circuit, the solid object enters the gap A in the overlapping part when the governor pressure generating device is in the state shown in Fig. 2, and in this state, by operating the shift lever, the In the situation shown in the figure, the solid matter got caught in the gap between the narrowed overlapping parts, causing valve stick.
本考案はかかるバルブスティックを防止できる流体式ガ
バナ圧発生装置の提供を目的とする。The present invention aims to provide a fluid governor pressure generating device that can prevent such valve sticking.
つぎに本考案を第３図に示す一実施例に基づき説明する
。Next, the present invention will be explained based on an embodiment shown in FIG.

においても弁体３の大径部３３とガバナボディの出入力
油路間の内壁２４とは重複（オーバーラツプ）しており
、その間隙Ａ“は巾が１０〜１００ミクロンの範囲にあ
るようにされている。The same reference numerals as in FIG. 1 indicate the same parts, and in the present invention, the large diameter portion 33 of the valve body 3 is formed to extend in the direction of the rotation axis 1, and the shift lever is shifted to the 2 and N positions. Under any operating conditions at the P, R, and N positions, the large diameter portion 33 of the valve body 3 and the inner wall 24 between the input and output oil passages of the governor body overlap (overlap), and the gap A between them overlaps. " has a width in the range of 10 to 100 microns.
重複部の間隙Ａ“の巾を１０〜１００ミクロンとしたの
は１０ミクロン以下だとガバナ圧の回転軸回転速度に対
する応答性が著しく悪くなるからであり、また切削くず
等のバルブスティックの原因となりやすい固形物は１０
０ミクロン以上のものが多く、１００ミクロン以上だと
重複部の間隙Ｎ’にこれら固形物が入りやすくなること
による。The reason why the width of the gap A" in the overlapping part is set to 10 to 100 microns is because if it is less than 10 microns, the responsiveness of the governor pressure to the rotational speed of the rotating shaft will be extremely poor, and it may also cause valve sticking such as cutting chips. The easiest solid food is 10
Most of the particles are 0 micron or larger, and if they are 100 micron or larger, these solid materials tend to enter the gap N' in the overlapping portion.
また重複部の間隙Ａ″は望ましくは１２〜５０ミクロン
の範囲が良くこの範囲がバルブスティックの防止効果お
よび応答性が良い。The gap A'' in the overlapping portion is preferably in the range of 12 to 50 microns, and this range provides good valve stick prevention effects and responsiveness.
以上の如く本考案の流体式ガバナ圧発生装置は入力路と
出力路を連絡するガバナボディと弁体との重複部の間隙
が１０ミクロン〜１００ミクロンであるようにしている
ので、間隙に切削くず等の固形物が挾まりにくくバルブ
スティックが防止できる。As described above, the fluid type governor pressure generating device of the present invention has a gap of 10 to 100 microns at the overlapping part between the governor body and the valve body, which communicates the input path and the output path, so that cutting waste does not remain in the gap. This prevents solid objects such as from getting stuck and prevents valve sticking.
