ABSTRACT OF THE DISCLOSURE A pump having a hollow cylinder, and a piston slidably received in the cylinder, with the piston dividing the inside of the cylinder into two chambers. A hollow piston rod has one end connected to the piston and the other end extending out of the cylinder, and means is provided for attaching the other end of the piston rod to an inflatable member. The pump has one-way valve means adjacent each end of the cylinder to permit passage of air into each chamber, while preventing passage of air out of the chambers. Valve means is carried by the piston to establish com- munication between either of the chambers and the piston rod when the pressure in either chamber exceeds the pressure in the piston rod and inflatable member. The pump has opening means communi- cating between the piston rod and one of the chambers, in order that the pressure in the inflatable member is indicated by the location which the cylinder assumes relative the piston after movement of the piston to the end of the one chamber and release of the cylinder.
