Abstract (en)
[origin: US4730403A] A sports shoe (1) is provided with air chambers underneath a comparatively rigid outer shell (2) such that pressure in these air chambers, i.e., the compression on the foot, can be adjusted by a pump system (5, 6). The design of the pump system is simple, easy to manufacture, compact and operationally reliable due to the valves (14, 15) of the pump system being enclosed in a common housing part (13) separated by a partition (20) from the membrane pump chamber (11). The valves (14, 15) are mounted coaxially in tandem sequence. The evacuating valve (15) can also serve as the pump suction valve and is provided at an end (37) with a manually displaceable stem which, during evacuation of the air chamber, wil make contact with the valve stem (b 32) of the pump pressure valve (14).
