Abstract
Abstract The valve is of the replaceable cartridge or unit type, and is constructed mainly of durable non-metallic materials which resist corrosion, wear, and adherence of foreign materials usually carried by the fluid under control of the valve; the valve featuring also a 90* limit of operating stem rotation and a minimum number of simple components capable of fabrication and assembly with great savings of time and labor so that the valve may be produced at low cost.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
237 words
A replaceable cartridge type fluid control valve for application to a faucet body having a bored neck-and-spout portion in fluid communicating relationship, comprising in combination: an axially bored cylindrical cartridge housing having open upper and lower ends, and intermediate delivery port means, an elongate operating stem having a key at one end, and a mount for an operating handle at the opposite end, said stem being supported for rotation within the housing bore; an openended cylindrical tailpiece secured to the lower end of the housing, and having an open fluid entry port and an internal port; a stationary valving member fixed to said tailpiece in spanning relation to said internal port, and having a ported, highly polished seat face disposed upwardly toward the stem; an adapter rotational within the housing, and having port means therein to communicate with the delivery port means of the housing and the internal port of the tailpiece; a rotary valving member rotational with the adapter, and having ports therein selectively communicative with the ports of the stationary valving member upon partial rotation of the adapter, said rotary valving member having a highly polished seat face flatly abutting the aforesaid seat face of the stationary valving member, the ports of said rotary valving member being in constant registry with the ports of the adapter; and cooperative means on the stem and the adapter, for translating rotary movements of the stem to said adapter.
