ABSTRACT:
A three-way valve housing is shown with side wall and end wall defined ports. A cylindrical plug member has oblong O-ring seals which jointly extend about a major portion of the plug members circumference. A central chamber in the plug member receives fluid through a laterally directed opening which is rotatable through less than 180 degrees into communication with a housing side wall port. The plug member chamber is in open communication with the port in the valve housing end wall. A snap ring is removable to permit extraction of the plug member from the housing for servicing purposes.
