Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
143 words
A diaphragm seal arrangement: a housing having a mechanism therein and having a through bore in a wall thereof; an actuator disposed in said bore and engageable with said mechanism to cause actuation and de-actuation thereof upon movement of said actuator; a diaphragm seal disposed about the outer opening of said bore and arranged for engagement with said actuator; and means for securing the outer periphery of said diaphragm seal to said housing and about the said outer opening comprising a retainer and a retainer fastening portion associated with said housing, said retainer having at least one resilient element snap fastened to, by being forced over, corresponding protrusions of said retainer fastening portion so said retainer engages and overlies the outer periphery of said diaphragm seal thereby causing the outer periphery to be maintained as a prisoner between said housing and said retainer.
