Title
(EN) HYDRAULIC PRESSURE WARNING DEVICE
(FR) DISPOSITIF D'AVERTISSEMENT DE PRESSION HYDRAULIQUE
(JA) 油圧警告装置
Abstract
(EN)
This hydraulic pressure warning device 100 issues a hydraulic pressure warning when an anomalous hydraulic pressure drop or clogging of an oil filter 101 has been estimated to be occurring. The hydraulic pressure warning device is provided with a control device 103 that: executes control so that a first hydraulic pressure warning is issued if an anomalous hydraulic pressure drop has been estimated to be occurring; and executes control so that a second hydraulic pressure warning is issued if clogging of the oil filter 101 has been estimated to be occurring.
(FR)
La présente invention concerne un dispositif d'avertissement de pression hydraulique (100) qui émet un avertissement de pression hydraulique lorsque la survenue d'une chute de pression hydraulique anormale ou d'un colmatage d'un filtre à huile (101) a été estimée. Le dispositif d'avertissement de pression hydraulique est pourvu d'un dispositif de commande (103) qui : exécute une commande de telle sorte qu'un premier avertissement de pression hydraulique soit émis si la survenue d'une chute de pression hydraulique anormale a été estimée; et exécute une commande de telle sorte qu'un second avertissement de pression hydraulique soit émis si la survenue du colmatage du filtre à huile (101) a été estimée.
