Embodiment Construction

[0071] First, referring to the attached Figure 1 to Figure 4 , shows a mixing valve 1 having a valve assembly 3 for mixing hot and cold water to provide a temperature-controlled water supply. The mixing valve 1 has a preferably cylindrical valve body 5 . The valve body 5 defines a volume 5 a for receiving the valve assembly 3 . The valve body 5 comprises two inlets 7a, 7b for hot and cold water and an outlet 9 for mixed water. The inlets 7a, 7b may be coupled to respective inlet shoulders 11a, 11b, and the inlet shoulders 11a, 11b may be connected to hot and cold water supplies via pipe connections 13a, 13b.

[0072] The valve assembly 3 includes: a thermostatic cylinder 15 for mixing hot and cold water supplies, which controls the temperature of the mixed water in response to actuation of a rotatable control member 17; The outflow of mixed water from the outlet 9 is controlled by actuation of the control member. In other embodiments, the cartridge 15 may be non-thermosta...

Abstract

A mixing valve (1) includes a body (5) extending in a first direction between a front end and a rear end. The body (5) defines a volume (5a); a thermostatic cylinder (15) is received in said volume (5a), and a diaphragm valve (21) is received in said volume (5a), located in said thermostatic cylinder (15) and the rear end of the main body (5). The diaphragm valve (21) is operable in response to actuation of a push-operated control member (23) to control the outflow of water from the mixing valve (1).

Description

technical field [0001] The present invention relates to faucets. In particular but not exclusively, the invention relates to a mixing valve comprising a diaphragm valve which can be activated by a push-operated control member. The invention also relates to a dual controller. In particular, but not exclusively, the present invention relates to dual controls having a push-operable control member and an independently operable rotatable control member. Background technique [0002] A mechanical mixer valve is a valve that mixes hot and cold water without requiring a power supply to operate. They can be used eg in showers. Typically, mechanical mixers allow the user to control the flow of water from the valve as well as the temperature of the water. In some arrangements, a single rotatable control member is provided for controlling temperature and flow. In other arrangements, separate rotatable control members are provided for independent control of temperature and flow. ...
