All pumps have a "one way" or "check" valve - otherwise, the air you just pumped into a tire/ball/whatever during the down-stroke, would come right back out in the up-stroke.
I have the same or similar pump as the one in your video - the check-valve is a simple rubber disk that sits in between the gage/air inlet assembly and the base assembly - it fell out when I took the pump apart.
I was really surprised at the amount of force the piston had with just a little air (40psi). This is going to work great for the prop I am building (I will post some picks when I am done - it may be a while)
