Dispenser for pressurized canister

An actuator control for a canister dispenser system, comprising:

• an actuator trigger having a finger operating web portion interconnecting spaced legs, each leg having a pivot positioned within a boss that extends below the finger operating web portion for supporting the actuator trigger on an axle, and each leg having an activation portion including a valve shoulder;
• a valve having a top stem connector attached to an output hose, a body portion with external support pins, a stem connector with an extended valve stem operably connected to an output of the canister,
• a canister connector that fits into the bottom housing and attaches to a valve gasket of the canister, and
• a trigger return spring with a spring coil surrounding the axle to bias the actuator trigger between a non-operating position wherein the contents do not flow out of the canister, and an operating position, wherein compression of the actuator trigger pivots the actuator control to move the valve shoulder to depress the external support pins and move the valve to engage the output of the canister and cause the contents to flow out of the canister via the output hose.

A method for dispensing contents from a pressurized canister for recharging a vehicle air conditioning system using a dispenser system comprising the steps of:

• removing a removable sensor from a sensor opening in a dispenser housing that holds the removable sensor and attaching it to a vehicle air vent;
• attaching a quick disconnect coupler on an output hose of the dispenser system to the vehicle air conditioning system;
• removing a removable lock pin from a locked position engaged with a lock shoulder within the dispenser housing to permit operation of an actuator control;
• actuating an actuator trigger of the actuator control by compressing an actuator trigger on a finger operating portion extending through a control opening through the dispenser housing, and pivoting the actuator trigger about a pivot positioned within a boss within the dispenser housing below the control opening supported on an axle engaged with the dispenser housing, engaging the actuator trigger on a valve shoulder with a movable valve having a top stem connector attached to the output hose, a body portion with external support pins for sliding engagement within valve supports within the dispenser housing, and a stem connector with an extended valve stem operably connected to an output of the canister, and biasing a trigger return spring to move the actuator trigger into the dispenser housing and an operating position, moving the valve shoulder and depressing the external support pins on the movable valve;
• causing the contents of the canister to flow out of the canister via the output hose and quick disconnect coupler to recharge the vehicle air conditioning system;
• and
• receiving instruction from the removable sensor to cease actuation of the actuator trigger and stop the contents of the canister from flowing out of the canister.
