Soap dispenser system and valve arrangement therefor

A soap dispenser system comprising:

• a suction tube including:
• a main through bore for supplying water from a water line pipe to a shower head, and
• a soap supply bore intersecting said main through bore;
• a soap dispenser positioned remote from the suction tube for controlling dispensing of soap from a container having soap therein;
• and
• a supply tube connecting the soap dispenser to the soap supply bore of the suction tube in order to provide soap from said soap dispenser to said suction tube by means of suction created by the water traveling through the main through bore of the suction tube;
• the soap dispenser including:
• an inner tube having an inlet and an outlet fluidly connected with said supply tube,
• an outer tube movably mounted over said inner tube and connected with the container, said outer tube having an inlet adapted to be fluidly connected with soap from the container and an outlet adapted to be fluidly connected with the inlet of the inner tube,
• a biasing device for applying pressure between said inner tube and said outer tube in a direction to move said inner tube and outer tube apart, said biasing device including a coil spring connected between said inner tube and said outer tube,
• a valve for permitting soap to enter said inlet of said inner tube when said outer tube is moved toward the inner tube against the force of said biasing device and which prevents soap from entering said inlet of said inner tube when said outer tube is moved away from the inner tube by said biasing device, and
• a free floating ball between said spring and said outer tube for providing a seal of the inlet of said outer tube when said outer tube is moved toward the inner tube against the force of said biasing device and which releases the seal of the inlet of said outer tube when said outer tube is maintained in a position moved toward the inner tube.

A soap dispenser system comprising:

• a suction tube including:
• a main through bore for supplying water from a water line pipe to a shower head, and
• a soap supply bore intersecting said main through bore,
• an outer surface having a recess therein, and
• a hollow central post in said recess which is in fluid communication with said soap supply bore, said hollow central post having a free end which substantially does not extend radially outward past said outer surface;
• a soap dispenser positioned remote from the suction tube for controlling dispensing of soap from a container having soap therein;
• and
• a supply tube connecting the soap dispenser to the scan supply bore of the suction tube in order to provide soap from said soap dispenser to said suction tube by means of suction created by the water traveling through the main through bore of the suction tube;
• the soap dispenser including:
• an inner tube having an inlet and an outlet fluidly connected with said supply tube,
• an outer tube movably mounted over said inner tube and connected with the container, said outer tube having an inlet adapted to be fluidly connected with soap from the container and an outlet adapted to be fluidly connected with the inlet of the inner tube,
• a biasing device for applying pressure between said inner tube and said outer tube in a direction to move said inner tube and outer tube apart,
• a valve for permitting soap to enter said inlet of said inner tube when said outer tube is moved toward the inner tube against the force of said biasing device and which prevents soap from entering said inlet of said inner tube when said outer tube is moved away from the inner tube by said biasing device.
