Abstract

A compressor/pump head (10; 100; 200) comprises a piston assembly (20; 120; 220) and a chamber-head assembly (30; 130; 230) defining a working chamber (60; 160; 260) between them. The piston assembly is fitted with a first diaphragm (26; 126; 260) and the chamber-head assembly is fitted with a second diaphragm (36; 136). The piston and chamberhead assemblies and their respective diaphragms form complementary relationship so that during compressing phase the two diaphragms form between them a progressive compliance contact until the working chamber's volume is reduced to virtually zero. In this way, the compressor head can achieve a high compression ratio by a relatively small stroke. Furthermore, the chamber-head assembly is fitted with a self-adjusting mechanism including a biasing spring (34; 134) and a cushioning arrangement (80; 180), which can adjust the chamber-head's position automatically in response to changes in outlet pressure. Such a position adjustment can compensate the stroke reduction of a linear drive when the working load is increased.
