Response to As I'm sure you know, I'm only kidding. Actually I'm a big fan of O-ring checkvalves...

In this design, the o'ring serves as the piston seal and the check seal; two way seal.

Pulling piston out forces ring against the piston face exposing the hole, which allows air in. Closing the piston forces the seal against a seat.
