ABSTRACT:
A fluid mixing device comprises a body part having an inlet for water under pressure, a main flow passage leading from the inlet to an outlet, the main flow passage being shaped to create a low pressure zone therein, and an auxiliary passage leading to the low pressure zone from a source of liquid detergent. The main flow passage is divided into two subsidiary passages downstream of the low pressure zone, and is formed in a valve member which is rotatable to prevent flow of fluid through at least one of said subsidiary passages, when required, thereby reducing the effective cross-sectional area of the main flow passage and creating back pressure which fills the low pressure zone and renders it ineffective in drawing the detergent into the main flow passage.
