    • The present invention includes an air valve having a housing (20) sealed to an inflatable device (1). The housing (20) includes an opening (22) that matingly receives a check valve (40) with an inner surface defining a passageway. A cap (60) is in turn matingly received in the passageway of the check valve (40). The housing (20), check valve (40), and cap (60) are all attached to and interconnected by a tether (30). During the inflation process, the check valve (40) is positioned in the opening (22) in the housing (20) and a source of pressurized air is delivered to the check valve (40) until the desired degree of inflation is achieved, at which time the cap (60) is inserted in the passageway of the check valve (40). To deflate the device, the end of the tether (30) is pulled up which acts to sequentially pull the cap (60) free from the passageway of the check valve (40) and pull the check valve (40) free from the opening (22) in the housing (20).
    • 本发明包括具有密封到充气装置(1)的壳体(20)的空气阀。 壳体(20)包括开口(22),该开口(22)配合地接纳具有限定通道的内表面的止回阀(40)。 盖(60)又配合地容纳在止回阀(40)的通道中。 壳体(20),止回阀(40)和盖(60)都通过系绳(30)附接到并由其连接。 在充气过程中,止回阀(40)定位在壳体(20)中的开口(22)中,并且加压空气源被输送到止回阀(40),直到达到期望的充气程度,在 该盖(60)插入止回阀(40)的通道中。 为了使装置放气,系绳(30)的端部被拉起,其作用是顺序地将帽(60)拉离止回阀(40)的通道,并将止回阀(40)从开口(40) 22)在壳体(20)中。
