Abstract

The valve construction comprises a valve housing which has a housing flow passage therethrough and an intermediate spherical valve chamber in the passage. A pivot member which has concentric end journal portions is rotatably mounted in the housing and has an intermediate eccentric portion which is offset from the end journal portions and is located in the valve chamber. A spherically shaped globe valve member having a valve flow passage therethrough opening at respectively diametrically opposite ends of the valve member is rotatably supported on the eccentric portion which extends through diametrically opposite walls of the globe valve member which has an axis at right angles to the axis of the valve flow path. A dog carried on the globe valve member projects outwardly therefrom into a groove of the housing and limits the movement of the globe valve member relative to the pivot to 90.degree.. The valve is opened by pivoting the pivot member to cause a pin which is carried on the globe member to ride in a 90.degree. arcuate groove defined in the pivot member and without rotating the globe member. Thereat, the pin bears against the end of the arcuate groove of the pivot member so tha…
