摘要: A device to enhance sealing is provided. The device includes a body and a pressure cup. The pressure cup includes a channel, a first pressure channel, and a second pressure channel. The channel is formed in a surface of the body to surround a first portion of the surface. The channel is configured to hold an o-ring. The first pressure channel extends through the body and opens into the first portion of the surface. The second pressure channel extends through the body and opens into the channel. Pneumatic pressure within the second pressure channel is controlled to hold the o-ring in the channel when a second pressure within the first pressure channel changes.
