International ClassesF16K 043/00F16K 011/22 AbstractA wall type shower faucet including a mixing valve and a faucet body having: first and second water inlet channels communicating with the mixing valve; a first load control passage in communication with the first water inlet channel; a second load control passage in communication with the second water inlet channel; a first rear passage communicating with the first water inlet channel; a second rear passage communicating with the second water inlet channel; a first water supply channel communicating with the first rear passage; and a second water supply channel communicating with the second rear passage. A junction pin cap is mounted in each first and second rear passage with a movable stem member mounted in each junction pin cap. Each movable stem member has a sealing washer and a tip portion extending into the associated load control passage. A spring member acts between each junction pin cap and the associated movable stem member to bias the sealing member into contact with the faucet body, thereby sealing off communication between the associated rear passage and load control passage. An adjustment pin cap is removably mounted in each load control passage, each adjustment pin cap having a filter screen and engaging the tip portion of one of the movable stem members to displace the sealing washer out of contact with the faucet body. When the adjustment pin cap is removed from the faucet body, the sealing washer is biased into sealing contact with the faucet body to prevent water leakage.Field of SearchFaucet type (e.g., domestic water use, etc.)Check valve disabled by normally movable main valve part Ball check Spring bias Escutcheon type support Wall Hollow strainer, fluid inlet and outlet perpendicular to each other Planar strainer normal to flow path Valve in each inlet Rotary Selective reciprocation or rotation Cleaning, repairing, or assembling WITH REPAIR, TAPPING, ASSEMBLY, OR DISASSEMBLY MEANS Flow path with serial valves and/or closures | |
