Abstract

Дозирующий жидкостной насос, содержащий всасывающий патрубок (2), снабженный всасывающим клапаном (3), сообщающимся с рабочей камерой (4), в которой возвратно-поступательно может перемещаться поршень, с открыванием всасывающего клапана, когда поршень (5) удаляется от патрубка, и нагнетанием с закрыванием всасывающего клапана и выходом жидкости через выходной клапан, что происходит при приближении поршня к патрубку; насос содержит между всасывающим клапаном (3) и рабочей камерой (4) устройство (D) для определения изменения давления, содержащее, с одной стороны, трубопровод (10), соединенный одним концом с рабочей камерой (4) и снабженный на другом конце всасывающим клапаном (3), и, с другой стороны, средство (11), чувствительное к давлению в трубопроводе, установленное в стенке трубопровода.
