Beschreibung
Zusammenfassung:	A two-line grease distribution system in which an automatic changeover valve passes grease to one of two lines alternately, both lines passing to a dispensing valve. The dispensing valve includes a piston member movable in a bore and valve means for connecting one line to the bore on one side of the piston whilst the bore on the other side of the piston is connected to a fluid outlet and vice versa. The automatic changeover valve is operated by variations of pressure in the system.
