ABSTRACT:
A dispensing valve unit (12) is provided (which may be a part of a cleaning brush unit (10)) having a stationary inner tubular assembly (22), a telescopically interfitted shiftable outer tubular assembly (24) and an inner dual valve assembly including valve body (26) operatively coupled with the outer assembly (24) and engageable with a shoulder (48) forming a part of the inner tubular assembly (22). The inner assembly (22) has a soap entry port (54) through a wall thereof, whereas the outer assembly (24) is equipped with a portion (90) adjacent the port (54) and having an opening (92) therethrough which is selectively registrable with the port (54). A cam mechanism (40, 80) between the inner assembly (22) and outer assembly (24) effects axial shifting of the outer assembly (24) upon rotation thereof. The outer assembly (24) is selectively shiftable so that the unit (12) may assume three different positions: a soap and low volume water delivery position wherein the opening (92) is in registry with the port (54) so that soap is drawn from an annular reservoir (112) formed between the assemblies (22, 24), and valve body (26) is shifted to permit controlled water flow therethrough so that soap and water are mixed for dispensing; a high volume water-only rinse position where the valve body (26) is shifted from shoulder (48) and portion (90) covers the port (54); and an all-off position where the valve body (26) engages shoulder (48) and prevents water flow through the valve body (26), and the portion (90) covers the port (54).
