“…Matos 15,16 carried out a numerical methodology to analyze the dynamic characteristics of reed type valve of refrigerating compressors and the transient force and flow were obtained and revealed. Lang 17 used a FSI methodology to study the dynamic behavior of valves in a hermetic reciprocating compressor and the overall performance were analyzed by varying suction valve parameters. Choi 18 and Hwang 19 investigated the valve dynamics in linear compressor by FSI method.…”

Miniature high pressure compressor (MHPC) is key component of continuous gas supply system in aircraft for missile launching and infrared cooling. Valve design makes a crucial role in reciprocating compressors and traditional valves in high-pressure reciprocating compressors usually occupy a large space, have relative larger clearance volume and spring stiffness, which are incompetent to be applied to MHPC. In this study, integrated reed valves with four cantilevers on a steel plate are proposed to serve as the suction valves and discharge valves in MHPC. By this method, the number of valve parts and the axial dimension can be greatly reduced. Theoretical research has been carried out to reveal the dynamic characteristics of the proposed integrated valves. Numerical methods based on equivalent model of cantilever valve are proposed to improve the calculating efficiency compared to traditional CFD method. The equivalent stiffness and equivalent mass for valve motion equations have been calculated and plugged into the whole mathematical models. Based on the optimized valve parameters, experimental investigation on MHPC has been carried out.

“…Buligan [19] developed a measurement method for compressor valve lift based on a single-point Laser Doppler Vibrometer (LDV), and this measurement required a special compressor case equipped with transparent windows for optical access to the valves. Based on Buligan's measurement method, Nagy [20] and Lang [21] validated their theoretical compressor and valve model and the adjustments were also carried out to study the effects of various valve parameters. Ludu [22] installed two endoscopes consisted of a thin fiber-optic bundle into the valve chamber so that valve movement could be obtained through clear pictures, and the valve lift was quantified by digital picture processing.…”
