Apparatus for dispensing cleaning fluids to an object

Claim 1

An apparatus for dispensing cleaning fluids to an object, at least two cleaning fluid supplies for said apparatus, a fluid-flow inlet line in respective fluid-flow communication with each of said supplies and being connectable to said object for the inlet flow of said fluids into said object, a fluid-flow outlet line in respective fluid-flow communication with each of said supplies and being connectable to said object for the outlet flow of said fluids from said object, a fluid-flow control valve respectively disposed in at least two of said outlet lines for controlling the flow of said fluids from said object and to said supplies and with said control valves being arranged to operationally open and close relative to fluid flow, the improvement comprising electrically powered means operatively associated with said control valve and being in at least said two of said outlet lines for operationally opening and closing said control valves in operational directions opposite to each other for the respective flow and blockage of the flow of fluids relative to said supplies, a fluid-flow one-way check valve respectively disposed in each of said inlet lines for blocking the flow of fluid in said inlet lines in the direction opposite said inlet flow into said object and thereby block the flow of fluid from said inlet lines and to said supplies before the fluid flows past said object, and an electric circuit, a fluid-flow electric pump electrically connected in said circuit and being in fluid flow communication with each of said supplies for respectively sequentially moving the fluids from said supplies through said inlet lines and said object and said outlet lines, for circulating said supplies through said apparatus in the sequence mentioned.

Claim 2

An apparatus for dispensing cleaning fluids to an object, at least two cleaning fluid supplies for said apparatus, a fluid-flow inlet line in respective fluid-flow communication with each of said supplies and being connectable to said object for the inlet flow of said fluids into said object, a fluid-flow outlet line in respective fluid-flow communication with each of said supplies and being connectable to said object for the outlet flow of said fluids from said object, a fluid-flow control valve respectively disposed in at least two of said outlet lines for controlling the flow of said fluids from said object and to said supplies and with said control valves being arranged to operationally open and close relative to fluid flow, the improvement comprising electrically powered means operatively associated with said control valve and being in at least said two of said outlet lines for operationally opening and closing said control valves in operational directions opposite to each other for the respective flow and blockage of the flow of fluids relative to said supplies, a fluid-flow one-way check valve respectively disposed in each of said inlet lines for blocking the flow of fluid in said inlet lines in the direction opposite said inlet flow into said object and thereby block the flow of fluid from said inlet lines and to said supplies before the fluid flows past said object, and an electric circuit, a fluid-flow electric pump electrically connected in said circuit and being in fluid flow communication with each of said supplies for respectively sequentially moving the fluids from said supplies through said inlet lines and said object and said outlet lines, for circulating said supplies through said apparatus in the sequence mentioned.

Claim 11
