Abstract
A dual control assembly for a shower fitting comprising a thermostatic valve in the form of a cartridge removably fitted in the mixing chamber of the fitting, and a flow rate valve, the two valves being operatively linked or coupled together, for example by a sleeve. The valves are co-axially aligned and provided with respective control knobs which are disposed at the same end of the shower fitting.
Claims18
A dual control assembly comprising a thermostatic valve in the form of a cartridge or unit insertable in a mixing chamber comprising:
- a shower fitting or other water outlet, a flow rate valve, and an operative link or coupling provided between the thermostatic valve and the flow rate valve, said flow rate valve being a self-contained unit.
A shower fitting or other water outlet including a mixing chamber in which is mounted a thermostatic valve in the form of a cartridge or unit, said fitting or water outlet having a flow rate valve operatively linked or coupled with the thermostatic valve, the thermostatic valve being controlled by a control knob mounted co-axially with a control knob for the flow rate valve and said two control knobs being mounted at the same end of the fitting or water outlet, the flow rate valve being a self-contained unit.
A dual control assembly comprising a thermostatic valve and a flow rate valve including an operating stem and a body portion, the arrangement being such that the body of the flow rate valve can be rotated relative to said stem to open and close the flow rate valve, the flow rate valve being a self-contained unit.
A dual control assembly, comprising:
- a thermostatic valve in the form of a cartridge or unit mounted in line with a flow rate disc valve, the body of which may be rotated relative to an operating stem held fixed, in use, relative to a mixing chamber or a shower fitting or other water outlet in which the dual control assembly is mounted, the flow rate valve being a self-contained unit.
A shower fitting or other water outlet having controls and including a dual control assembly comprising a thermostatic valve in the form of cartridge or unit insertable in a mixing chamber of the shower fitting or other water outlet, and a flow rate valve, and in which an operative link or coupling is provided between the thermostatic valve and the flow rate valve, the flow rate valve being mounted toward the front of the mixing chamber, towards said controls, and the thermostatic valve being mounted toward the rear.
A dual control assembly having a thermostatic valve in the form of a cartridge or unit with two concentrically mounted control knobs, the one control knob being for controlling the thermostatic valve and the other control knob being for controlling the flow rate valve operatively coupled to the thermostatic valve, the flow rate valve being a self-contained unit.
A dual control assembly having a thermostatic valve aligned with a flow rate valve in a fluid mixing chamber of a fitting or water outlet, the thermostatic valve and flow rate valve being controlled from the same end of the fitting or outlet by coaxially arranged control knobs, the flow rate valve being a self contained unit.
