Abstract
A housed valve which serves to control the flow therethrough of a medium is disclosed. The valve comprises a control member which projects into a flow-through aperture and is supported flexibly and elastically on a guide wire attached to the housing. The guide wire may be made of steel wire, and the support in a fixed relationship with the housing may be such that the axial position of the control member with respect to the flow-through aperture can be influenced in accordance with temperature.
