ГИДРАВЛИЧЕСКИЙ ДОВОДЧИК ДВЕРИ

Номер: RU0000196446U1

Полезная модель относится к устройствам для закрывания и открывания с тормозными приспособлениями, а именно - к устройствам для закрывания и открывания с гидравлическими поршневыми тормозами, гидравлические тормозные устройства с пружинами, оси которых совпадают с осью поршня, и клапанными устройствами. Полезная модель может быть использована для дверей одностороннего и маятникового типа открывания в жилых, производственных и общественных зданиях на наружных и внутренних дверях для их плавного закрывания. Техническим результатом является повышение срока службы доводчика двери. Технический результат достигается тем, что гидравлический доводчик двери содержит: корпус с заполненным рабочей жидкостью внутренним пространством, выполняющим функцию гидроцилиндра; два установленных в гидроцилиндре поршня: возвратный и демпферный с установленными в них роликами; расположенный между роликами приводной вал с кулачком; возвратную пружину; переднюю крышку корпуса с механизмом регулирования усилия возвратной пружины; заднюю крышку корпуса и демпферную пружину, установленную между задней крышкой и демпферным поршнем; установленные в демпферном поршне обратный клапан и предохранительный клапан; гидравлические каналы с регулирующими вентилями, связывающие разделенные демпферным поршнем камеры внутреннего пространства гидроцилиндра; при этом демпферный поршень выполняет функцию золотника, перекрывающего и открывающего по ходу своего движения в гидроцилиндре гидравлические каналы, изменяя, тем самым, скорость закрывания двери. Полезная модель отличается наличием поршневого компенсатора ударного давления, состоящего из работающей на сжатие компенсаторной пружины и поршня компенсатора, которые в указанном порядке установлены в глухое отверстие, выполненное в демпферном поршне со стороны задней крышки корпуса доводчика. 7 ил.
