Document Type and Number:
Japanese Patent JP2000514527
Kind Code:
A
Abstract:
By means of an activating pin for a valve connector, which activating pin is designed as a piston (301) with a piston rod (302), moving in the coupling house of the valve connector where the activating pin has a central drilling (303) and a piston valve (304) kept closed by a spring force, the aim is to produce a reliable activating pin which is reliable, cheap, has low aerodynamic drag and thus, is comfortable to use for pumping purposes and provides the shortest possible pumping time. Pursuant to the invention, this is achieved by the fact that one or more channels (303,321) are defined by the piston rod (302) and/or the piston valve rod (322) in the assembled activating pin which channels (303,321) are positioned in a mainly longitudinal direction in relation to the centerline (337) of the activating pin, of which the cross section approximately can be defined by at least one closed curve, which can be defined by two unique modular parametrisation Fourier Series expansions.
