摘要 |
An apparatus includes a valve housing having an inlet port, a first chamber with a first outlet port, and a second chamber with a second outlet port. A first valve opens between the inlet port and the first chamber under a first level of pneumatic pressure at the inlet port. A second valve opens between the first chamber and the second chamber under a second, greater level of pneumatic pressure in the first chamber. A third valve opens between the second chamber and the first chamber under a third level of pneumatic pressure in the second chamber, with the third level being less than the first level.
