The paper aims at the determination of the maximum output pressure as one of the pertinent parameters describing the steam injector performance. Experimental and theoretical results of discharge pressure investigation from steam-water injector are presented. Experiments included measurements of output pressure dependence on varying inlet flow rates of both media and on the water nozzle gap. Maximum output pressure obtained reached 97% of the inlet vapour pressure. Performance of the steam injector is described mathematically using momentum balance in mixing chamber and shock wave region. Loss coefficient of the steam injector is also determined. Having the loss coefficient one can evaluate the maximum pressure for geometry similiar steam injectors. From the analysis of the balance equations, the ways of increasing the maximum discharge pressure are suggested.
