Abstract
A valve including a body and a plug is disclosed. The body has a pair of ports and a tubular structure having a side wall and an open end and defining interiorly a first subchamber communicating with one port. The wall has an opening. The body defines a second subchamber communicating with the other port, extending around the wall and beyond the end to communicate with the end and the opening. The plug has an opening, is mounted to the structure and telescopes between first and second positions. At the second position, the plug is disposed at least partly in the second subchamber and the valve defines, between the ports: a first flow path through the wall opening; and a second flow path through the open end of the structure, via the plug opening. At the first position, the plug and structure restrict flow through the first and second paths.
