It's likely there's a rupture in the diaphragm that pulls the air into the chamber and then pushes it out to the valve.
There are two "reed" valves in the pump that only allows the air to go in one direction with each valve. So when you pull up on the handle to fil the pump, one valve allows air in, but not out when you push down on the handle. Another valve at the bottom of the pump allows the air out when the handle is pushed down, going to the tire. There is another vavle on the tire that is opened only with the pumps adaptor, to allow air into the tire.
