MIXING CHAMBER FOR GENERATING A PUMP CHARGE

Abstract: a mixing chamber for generating a pump charge in a fluid pump has an inner wall defining an inside space. a suction inlet is configured to be connected to a fluid source from which it draws a fluid. a charging inlet is configured to admit a fluid stream into the inside space and thereby to generate the pump charge. an outlet from the inside space is configured to let the fluid in the inside space out of the mixing chamber. the charging inlet includes a first fluid-guiding section configured as a confuser, a second fluid-guiding section in the form of a constriction, and a third fluid-guiding section configured as a diffuser. the constriction is located between the confuser and the diffuser and has the smallest diameter within the charging inlet. the diffuser is formed by an inclined side surface.
