Abstract:
1. A system for inflating an inflatable element with a liquid inflating medium, the system comprising: a separating means for separating the liquid inflating medium from a gaseous medium therein, a flow line communicating the inflatable element with the separating means, a return line communicating the inflatable element with the separating means, a pump means selectively operable to alternately deliver the liquid inflating medium from the separating means to the inflatable element and from the inflatable element to the separating means, and a valving means communicating the separating means with the flow line and the return line, the valving means being configured to permit flow of the liquid inflating medium from the separating means to the inflatable element through the flow line and to prevent flow of the liquid inflating medium from the separating means to the inflatable element through the return line during inflating of the inflatable element, and to permit flow of the liquid inflating medium from the inflatable element to the separating means through the return line and to prevent flow of the liquid inflating medium from the inflatable element to the separating means through the flow line during deflating of the inflatable element.
