Liquid dispenser with flow control

A liquid dispenser comprising:

• a dispenser body having a pump mechanism, an intake port adapted for fluid communication with a source of liquid, an intake liquid flow path providing fluid communication between the intake port and the pump mechanism, a first check valve in the intake liquid flow path configured for permitting fluid flow from the intake port to the pump mechanism and for checking fluid flow from the pump mechanism to the intake port, a discharge port, a discharge liquid flow path providing fluid communication between the pump mechanism and discharge port, and a second check valve in the discharge liquid flow path configured for permitting fluid to flow downstream from the pump mechanism to the discharge port and for checking fluid flow from the discharge port to the pump mechanism;
• and
• a flow restrictor in the discharge liquid flow path moveable relative to the dispenser body between a first position in which the flow restrictor is spaced a first distance from the discharge port of the dispenser body and a second position in which the flow restrictor is spaced a second distance from the discharge port;
• said dispenser body and flow restrictor cooperating for dispensing liquid from the discharge port in a first dispensing pattern when the flow restrictor is in its first position and for dispensing liquid from the discharge port in a second dispensing pattern when the flow restrictor is in its second position, the first dispensing pattern differing from the second dispensing pattern.

• a spinner member in the discharge liquid flow path moveable relative to the dispenser body between a first position in which the spinner member is spaced from the discharge port of the dispenser body and a second position in which the spinner member is adjacent the discharge port;
• said dispenser body and spinner member cooperating for dispensing liquid from the discharge port in a first dispensing pattern when the spinner member is in its first position and for dispensing liquid from the discharge port in a second dispensing pattern when the spinner member is in its second position, the first dispensing pattern differing from the second dispensing pattern.
