Abstract

Jeringa de estanqueidad constante para operar a altas y a bajas temperaturas. La jeringa tiene una carcasa (1) en cuyo interior se encuentra el barril (2), la unión de éste con la carcasa se realiza con la junta (11) que se comprime con el resorte (13). La aguja se fija a la carcasa (1) mediante una junta cónica (5) que se comprime con el resorte (8). La punta del émbolo (16) es cilíndrica y tiene dos pestañas o aletas que están inclinadas hacia el exterior del eje del émbolo, estas aletas encajan entre el vástago (15) y el tirante (17) y se ensanchan mediante el sistema que está en el interior de la cabeza del émbolo. Este sistema está formado por la guía (20), el resorte (25) y las piezas (18) y (23). Las dilataciones de los materiales producidas por las variaciones de temperatura se compensan en todas las uniones mediante los resortes. Esta jeringa tiene aplicación en los laboratorios de ensayos.
