Abstract:
1. A fluid dispensing system comprising: a solenoid control valve assembly housing; a solenoid control valve member disposed within said solenoid control valve assembly housing and movable between first and second positions; an electrical connector mounted upon a first side wall portion of said solenoid control valve assembly housing for providing electricity to said solenoid control valve member; a pair of inlet supply and outlet exhaust passages defined within said first side wall portion of said solenoid control valve assembly housing and fluidically connected to said solenoid control valve member so as to supply and exhaust control air to and from said solenoid control valve member; a fluid control module assembly having a dispensing valve assembly disposed therein, wherein said dispensing valve assembly comprises a dispensing valve member and a valve stem, and wherein said fluid control module assembly also has a control piston disposed therein which is coaxially mounted upon said valve stem and which is disposed within an air control chamber also defined within said fluid control module assembly; a pair of bores defined within said fluid control module assembly fluidically connected to said air control chamber within which said control piston is disposed; and a pair of fittings projecting outwardly from a second side wall portion of said solenoid control valve assembly housing, which is disposed opposite said first side wall portion of said solenoid control valve assembly housing upon which said electrical connector is mounted and within which said pair of inlet supply and outlet exhaust passages are defined, wherein said pair of fittings respectively define first and second fluid passages which have upstream end portions fluidically connected to said solenoid control valve member and said inlet supply and outlet exhaust passages, while downstream end portions of said pair of fittings are adapted to be mated within said fluid control module assembly so as to be fluidically connected to said pair of bores defined within said fluid control module assembly, which has said control piston and said dispensing valve assembly disposed therein, such that when said solenoid control valve member is disposed at said first position, said inlet supply passage is fluidically connected to said first fluid passage of said pair of fittings and to a first one of said pair of bores defined within said fluid control module assembly such that said control air is supplied to said air control chamber in order to move both said control piston and said dispensing valve member in a first direction so as to permit the dispensing of a fluid, and said second fluid passage of said pair of fittings is fluidically connected to said outlet exhaust passage, while when said solenoid control valve member is disposed at said second position, said inlet supply passage is fluidically connected to said second fluid passage of said pair of fittings and to a second one of said pair of bores defined within said fluid control module assembly such that said control air is supplied to said air control chamber in order to move both said control piston and said dispensing valve member in a second direction so as to prevent the dispensing of a fluid, and said first fluid passage of said pair of fittings is fluidically connected to said outlet exhaust passage.
