<p>A mixing valve for a faucet includes a faucet body with a chamber that receives a cartridge and a bore that receives a piston. The piston has passageways therethrough in communication with inlets of the body and also in communication to entrances in the cartridge. The piston has a passage leading to a chamber that is interposed between the piston and the body that is responsive to hydraulic pressure from one of the inlets to create a bias that presses against the cartridge and transfers compressive force to a moving valve plate and a fixed valve plate that are within the cartridge. Furthermore, a supplemental spring is interposed within the hydraulic chamber to give mechanical upward bias of the piston against the cartridge.</p> |
