The arrangement is such that the complete unit comprising all the movable component elements of the faucet can be removed as a unit by using a simple, conventional spanner.，下面是Mixing faucet专利的具体信息内容。

权利要求

1. A thermostatic mixing faucet adapted, from a supply of hot fluid and a supply of cold fluid, to deliver a mixed fluid output at a predetermined temperature, which comprises a faucet body having an axial bore and having two lateral inlets at its lower portion for supplying said hot and cold fluids respectively, a valve chamber formed in said lower portion, holes connecting said inlets to the lower and upper portions of said valve chamber, respectively, a moveable member, a spool valve mounted for vertical sliding movement in said valve chamber and provided with upper and lower seals and adapted to travel from a first end position in which said lower seal engages the bottom of said valve chamber in a fluid-tight manner to prevent the ingress of one fluid into said valve chamber and another end position in which said upper seal engages the top of said valve chamber consisting of the bottom portion of said moveable member from preventing the ingress of the other fluid into said valve member, said moveable member having a polygonal sectional shape and being housed in a part of corresponding shape of the faucet body in order to allow an axial movement of the moveable member while preventing any rotation thereof, a central hole in the bottom portion of said moveable member for the ingress of hot and cold fluids and at least one opening in the lateral wall of said moveable member registering with an outlet of the faucet body for the egress of the mixed fluid, a handle in threaded engagement with the external face of said faucet body and adapted by a rotational movement to move axially in relation to said faucet body, said handle co-acting with said moveable member to move this latter axially without causing it to rotate, a thermostatic capsule housed axially within said moveable member and co-acting at its upper end with an upper wall of said moveable member under the action of a spring, while the lower part of said thermostatic capsule is rigidly connected to said valve spool by means of an axial rod passing through the central opening of the bottom portion of said moveable member, and means for adjusting from the outside of said faucet body the position of said thermostatic capsule within said moveable member.

2. Thermostatic mixing faucet according to claim 1, wherein means for adjusting the position of said thermostatic capsule consist of a sleeve member positioned internally at the upper part of said moveable member in threaded engagement therewith and adapted to be rotated from the outside of said faucet body to move axially within said moveable member, said upper wall of said moveable member being supported by internal lower shoulders of said sleeve member and being forced against said shoulders by a spring housed within said sleeve member and bearing at its upper end on a transverse upper cap of said sleeve member.

3. Thermostatic mixing faucet according to claim 2, wherein said transverse upper cap is in threaded engagement with the upper end of the lateral wall of said sleeve member and capable of being rotated to move axially with respect to said sleeve member for adjusting the force exerted by said spring.

4. Thermostatic mixing faucet according to claim 2, wherein a control rotating cap provides the axial movements of said sleeve member by rotatably driving its upper, polygonal-sectional contour of said control rotating cap.
