Filed:

Aug 28, 2009

Appl. No.:

12/549383

Inventors:

CHI F. WANG - San Marino CA, US

International Classification:

F16D 55/26

US Classification:

188 726

Abstract:

A hydraulic brake lever assembly includes a hollow lever mount accommodating therein a hydraulic pump. Two window openings are respectively formed in opposite sides of a middle section of the lever mount and in communication with an interior space of the lever mount. The hydraulic pump includes an outer cylinder member and an inner bore member arranged inside the outer cylinder member to define a hydraulic fluid chamber therebetween. An in-flow passage is defined in a wall of the inner bore member to communicate a bore defined in the inner bore member. A spring-biased piston is movably received in the bore of the inner bore member. The piston is driven by a driving bar coupled to a handgrip. The outer cylinder member forms in a wall thereof a hole receiving and in threading engagement with a transparent plug that is exposed through each of the window openings.

Abstract:

Engineered surfaces, such as surfaces having nano- and/or micro-scale features, may provide an enhanced flow boiling Critical Heat Flux (CHF) at ambient or higher pressures, which may enhance cooling. Enhancing flow boiling CHF may be desirable for nuclear reactors, where heat is generated by a heater such as a nuclear reactor core. Enhanced flow boiling CHF may provide larger safety margins and/or better economics of nuclear reactors, for example, because reactor power rating may be increased as cooling is enhanced.
