CLOSER DEVICE
To facilitate an operation of regulating a door closing speed using a DA speed regulating valve.SOLUTION: A closer device 10 comprises: a housing 11 having an oil chamber 12 filled with hydraulic oil; a piston 19 for dividing the oil chamber 12 into a first oil chamber 12a and a second oil chamber 12b; a piston drive mechanism for driving the piston 19; a rotating shaft 14 for rotating by being connected to an external opening/closing body; and a control mechanism part for controlling an opening/closing operation of the opening/closing body by regulating an amount of hydraulic oil moved between the first oil chamber 12a and the second oil chamber 12b accompanying a reciprocal movement of the piston 19. The control mechanism part includes: at least one hydraulic oil passage 41 for connecting the first oil chamber 12a and the second oil chamber 12b and circulating the hydraulic oil between both oil chambers; a main regulating valve 23 for regulating and throttling a flow passage cross-sectional area of the hydraulic oil passage 41; and an auxiliary valve 24 for throttling the flow passage cross-sectional area of the hydraulic oil passage 41 to be a predetermined value.SELECTED DRAWING: Figure 2
【課題】ＤＡ速度調整弁を用いた閉扉速度調整作業を容易化する。【解決手段】このクローザ装置１０は、作動油が充填される油室１２を備えるハウジング１１と、油室１２を第１の油室１２ａと第２の油室１２ｂに分割するピストン部１９と、ピストン部１９を駆動するピストン駆動機構部と、外部の開閉体と連結されて回転する回転軸１４と、ピストン部１９の往復移動に伴う第１の油室１２ａおよび第２の油室１２ｂ間での作動油の移動油量を調整して開閉体の開閉動作を制御する制御機構部と、を備え、制御機構部は、第１の油室１２ａと第２の油室１２ｂを接続して両油室間の作動油の流通を行う少なくとも１つの作動油経路４１と、作動油経路４１の流路断面積を調整可能に絞るメイン調整弁２３と、作動油経路４１の流路断面積を所定値に絞る補助弁２４と、を備える。【選択図】図２
