Regulating mechanism for the service adapter of a service coupling cooperating with a charging port part
First Claim
1. A service adapter comprising:
- (a) a hollow adapter body;
(b) means for defining a valve seat in the adapter body;
(c) a threaded spindle threadedly engaging said adapter body and extending thereinto;
(d) a turning knob attached to said spindle, whereby a rotation of the turning knob effects a rotation and a linear displacement of the spindle relative to the adapter body;
(e) a valve stem disposed in said adapter body and adjoining said spindle;
(f) a valve body attached to said valve stem and cooperating with said valve seat; and
(g) coupling means connecting said spindle with said valve stem for transmitting from said spindle to said valve stem forces derived substantially solely from the linear displacement of the spindle, whereby no appreciable tangential forces are applied to said valve stem to substantially prevent rotation of said valve stem and said valve body.

Abstract
A service adapter includes a hollow adapter body; a valve seat in the adapter body; a threaded spindle threadedly engaging the adapter body and extending thereinto; a turning knob attached to the spindle, whereby a rotation of the turning knob effects a rotation and a linear displacement of the spindle relative to the adapter body; a valve stem disposed in the adapter body and adjoining the spindle; a valve body attached to the valve stem and cooperating with the valve seat; and a coupling connecting the spindle with the valve stem for transmitting from the spindle to the valve stem forces derived substantially solely from the linear displacement of the spindle. In this manner no appreciable tangential (circumferential) forces are applied to the valve stem to substantially prevent rotation of the valve stem and the valve body.
