Fluid dispenser system

A fluid dispenser system configured to switch between an open valve position in which fluid flows through a fluid channel and a closed valve position in which fluid is prevented from flowing through the fluid channel, the system comprising:

• a valve disposed along the fluid channel and configured to move between the open valve position and the closed valve position;
• a trigger actuatable between an open trigger position and a closed trigger position which move the valve between the open valve position and the closed valve position, respectively;
• a trigger latch configured to move between a latched position in which the trigger latch fixes the trigger in the open trigger position and an unlatched position in which the trigger latch does not constrain movement of the trigger;
• and
• a solenoid with a solenoid pin, the solenoid configured to translate the solenoid pin between an extended position capable of retaining the trigger latch in the latched position and a retracted position that allows the trigger latch to move into the unlatched position,
• wherein the trigger latch includes at least one roller that extends substantially perpendicular to the solenoid pin, the solenoid pin being in contact with the at least one roller to hold the trigger latch in the latched position and not in contact when in the unlatched position.
