Claims (1)
せるチヤージポンプの吐出量に基づくオリフイス
差圧によりサーボレギユレータを介してメインポ
ンプの吐出量を制御する油圧伝導装置において、
上記オリフイスの前後を短絡するバイパス通路を
設け、このバイパス通路にエンジンアイドル回転
域で開いてオリフイス差圧の発生を抑制する中立
バルブを介装したことを特徴とする油圧伝導装置
。 In a hydraulic transmission device that controls the discharge amount of the main pump via a servo regulator based on the orifice differential pressure based on the discharge amount of the charge pump that is driven integrally with the main pump by the engine,
A hydraulic transmission device characterized in that a bypass passage is provided that short-circuits the front and back of the orifice, and a neutral valve that opens in the engine idle rotation range and suppresses the generation of orifice differential pressure is interposed in the bypass passage.
