Description

ри него штоком с эластичной мембраной, отличающийс  тем, что, с целью упрощени  конструкции и иовышенн  срока службы, параллельно мембране установлена дополнительна  мембрана, соединенна  с первой по периферии, а на внутренней поверхности корпуса выполнена выточка дл  создани  зазора переменного сечени .Here, a rod with an elastic membrane, characterized in that, in order to simplify the construction and increase the service life, an additional membrane is installed parallel to the membrane along the first periphery and an undercut to create a gap of variable cross section on the inner surface of the housing.
