Suction cup with basic piece - has base joined to vacuum suction unit, and has casing, and vacuum chamber with through-holes

摘要

The suction cup (10) consists of a basic piece (12) joined by a connection to a vacuum suction-unit. A suction-casing (14) is a one piece extension to the basic piece (12). Inside the suction-cup (10) is a vacuum-chamber (16) connected to the inside of the suction-casing (14). Through-holes (26a-26c) of smaller dia. connected the vacuum chamber (16) with one suction surface of the suction case (14). Partitions (24a-d) enclose the holes (26a-c) and form a number of small vacuum chambers. USE/ADVANTAGE - The theoretical quantity of adhesive force can be easily and reliably calculated, and the vacuum easily produced.
