To provide an impurity removal system for a towed vehicle, which removes impurity and can improve safety of the towed vehicle by allowing compressed air to be distributed even when an operation error occurs.SOLUTION: An oil separator 2 for a towed vehicle includes housing 3 provided with an inlet portion 30, an outlet portion 31, a communication portion 32 allowing communication between the inlet portion 30 and the outlet portion 31, and a valve portion 33 disposed in the communication portion 32 in a valve closed state where distribution of compressed air between the inlet portion 30 and the outlet portion 31 is limited, configured to, when a pressure difference of the inlet portion 30 to the outlet portion 31 is higher than a first predetermined value, shift to a first valve opened state where the compressed air is allowed to be distributed from the inlet portion 30 not via a filter cartridge 4 to the outlet portion 31, and configured to, when a pressure difference of the inlet portion 30 to the outlet portion 31 is higher than a second predetermined value, shift to a second valve opened state where the compressed air is allowed to be distributed from the outlet portion 31 not via the filter cartridge 4 to the inlet portion 30.SELECTED DRAWING: Figure 3
【課題】不純物を除去するとともに、動作不良が発生した場合でも圧縮空気の流通を可能とすることで、被牽引車両の安全性を向上することができる被牽引車両用の不純物除去システムを提供する。【解決手段】被牽引車両用のオイルセパレータ2であって、ハウジング3は、入口部30と、出口部31と、入口部30と出口部31との間を連通する連通部32と、入口部30と出口部31との間の圧縮空気の流通を制限する閉弁状態で連通部32に設けられ、出口部31に対する入口部30の圧力差が第1の所定値よりも高い場合、フィルタカートリッジ4を経由せずに入口部30から出口部31への圧縮空気の流通を可能にする第1の開弁状態に移行し、入口部30に対する出口部31の圧力差が第2の所定値よりも高い場合、フィルタカートリッジ4を経由せずに出口部31から入口部30への圧縮空気の流通を可能にする第2の開弁状態に移行する弁部33とを備える。【選択図】図3
