SELF-RETURNING CONTAMINATION BARRIER |
摘要 |
A barrier of a vacuum pump prevents contamination from entering a vacuum pump air line. The barrier separates parts of the pump and is moveable betwe en an initial state and a distended state. The barrier is assembled within t he pump with a pre-load. When the vacuum source is applied to the barrier, t he barrier achieves a distended state and when the vacuum source is released , the barrier incrementally self returns to an initial state. The geometry a nd material construction of the barrier, along with the pre-load, assists in returning the barrier on its own to the initial state from the distended st ate. |
