係止機構を備えたシングルレバー温/冷水栓上で使用される温水側のみのスプリングリターン
Document Type and Number:
Japanese Patent JP2012511125
Kind Code:
A
Abstract:
A faucet includes a valve body having a cartridge receiving bore. A valve cartridge is sealingly disposed in the bore. The valve cartridge includes a rotatable stem. An arc-shaped slot is created in the valve cartridge. A lever assembly having a single handle is connected to the stem and operates when rotated in a first direction to permit cold water flow through the valve body, and after being depressed can be rotated in an opposite second direction to permit hot water flow through the valve body. A torsion spring has a first post received in the elongated slot translatable between opposed ends of the elongated slot, and a second post received in a lever assembly aperture preventing second post translation. A biasing force of the torsion spring biases the lever assembly toward a valve closed position only when the lever assembly is rotated in the second direction.
