Abstract

Демпферное устройство для поршневого насоса, содержащее частично заполненную воздухом вертикальную трубку (1), установленную на впуске (2) поршневого насоса, а также частично заполненную воздухом вертикальную трубку (3), установленную на выпуске (4) поршневого насоса. Обе вертикальные трубки (1, 3) взаимно соединены друг с другом при помощи отсечного клапана (6). Каждая из вертикальных трубок (1, 3) соединена с соответствующим воздухозаборным клапаном (7, 8). Оба воздухозаборных клапана (7, 8) соединены с общим источником сжатого воздуха. Демпферное устройство достаточно просто может быть адаптировано для асептической работы и/или для повышенного давления продукта.Международная заявка была опубликована вместе с отчетом о международном поиске.
