Abstract:

A pressure regulator for controlling the flow of gas from a high pressure source to a low pressure device and regulating a pressure to the low pressure device includes a body having a high pressure inlet and a regulated pressure outlet. The body has a series of passages and bores including first and second regulator valve assembly bores and first and second fill valve assembly bores. The first and second regulator valve assembly bores are disposed on opposing sides of one of the passages and the first and second fill valve assembly bores are disposed on opposing sides of one of the passages. A regulator valve assembly includes a seal, a regulator valve piston, a biasing member and an adjusting plug positioned in the first regulator valve assembly bore, and a seal, a seat, a ball, a spring and a plug positioned in the second regulator valve assembly. A fill valve assembly includes a seal, a jam nut, a spring, a valve shaft, and a shaft actuator positioned in the first fill valve assembly bore and a seal, a seat, a ball, a spring and a plug positioned in the second fill valve assembly bore.

Abstract:

Bicycle disc brake rotors of the present invention are lightweight, have relatively high coefficients of friction to maintain braking friction under heavy braking, and quickly shed heat. The parts may preferably be made from a compound having carbon fiber and/or a refractory material, such as ceramic filler, within a polycarbosilane polymer resin, the polymer resin having a silicon-oxygen polymer backbone, producing silicon oxycarbides upon pyrolysis. Methods of making and using the same are further provided.
