Title
(JA) 斜板ポンプ用制御システム
Abstract
(JA)

油圧システム用のポンプ(10)が開示される。ポンプは、傾斜可能な斜板(28)と、斜板を傾けるために移動可能な少なくとも1つのアクチュエータ(34)と、加圧流体供給部(42)と、ドレーン(52)とを有することができる。ポンプはまた、加圧流体供給部およびドレーンに接続可能であり、少なくとも1つのアクチュエータの動作を制御するように構成された第1の回路(48)と、加圧流体供給部およびドレーンに接続可能であり、少なくとも1つのアクチュエータの動作を制御するように構成された第2の回路(50)とを有することができる。ポンプは、通常運転状態時に、第1の回路を供給部およびドレーンに接続し、フェイルセーフ状態時に、第2の回路を供給部およびドレーンに接続するように構成された弁(58)をさらに有することができる。
