Abstract

A 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.

Claims

1. A wall type shower faucet including a mixing valve and comprising;

a) 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;

b) a junction pin cap mounted in each first and second rear passage;

c) a movable stem member mounted in each junction pin cap, each movable stem member having a sealing washer and a tip portion extending into the associated load control passage;

d) a spring member acting between each junction pin cap and the associated movable stem member so as to bias the sealing washer into contact with the faucet body, thereby sealing off communication between the associated rear passage and load control passage;

e) adjustment pin caps removably mounted in the load control passages, said adjustment pin caps having plug blocks disposed therein, said plug blocks receiving an outermost portion of said stems opposite said sealing washers, the adjustment pin caps having filter screens surrounding a portion of said stems between said plug blocks and said sealing washers, wherein movement of said adjustment pin caps against said plug blocks move the movable stem members to displace the sealing washers out of contact with the faucet body thereby enabling water to flow into the water supply channels, the rear passages, the load control passages and through the filter screens before entering the water inlet chambers, whereby removal of the adjustment pin caps from the faucet body enables the sealing washers to be moved into sealing contact with the faucet body, while at the same time removing said plug blocks and said filter screens for servicing said filter screens from said outermost stem portions.
