<p>A valve housing has a circular cylindrical tubular member and a tubular body having a central portion which is substantially rectangular in cross-section and has mutually opposite, first and second side walls. The first side wall has in cross-section a length equal to the diameter of said tubular member, which is joined to said first side wall and extends at right angles thereto. A motor-operable valve member is axially slidably mounted in said tubular member and comprises a laterally open shell, which consists of a part of a circular cylinder and is coaxial to said tubular member and substantially defined by that cross-sectional plane of said central portion which includes the axis of said tubular member, a circular ring at the end remote from said second side wall, and an end wall at the end opposite to said circular ring.</p> |
