Abstract: A high pressure washing system wherein the positive action displacement pump is continuously starved and the variable pressure water supply is controlled to reduce the pressure applied thereby to the feed lines to the pump at essentially zero with the result that the ratio of water to cleaning solution can be metered accurately irrespective of substantial variations in pressure of the source of supply. Essentially any desired ratio can be obtained and accurately maintained by adjustment of the orifice of a valve in the cleaning solution line, once the improved control device has been adjusted for the approximate range.
Abstract translation: 一种高压清洗系统,其中正作用位移泵连续地饥饿,并且控制可变压力水供应,以将由此施加的泵施加的压力基本上为零,结果是水与清洗溶液的比例可以 准确计量,而不管供应来源的压力有多大变化。 一旦将改进的控制装置调整到近似的范围,就可以通过调整清洗液管线中的阀的孔而获得并准确地维持任何期望的比例。
