Abstract: A dispenser, method and system using a pressurized canister of cleaner for removing deposits from GDI engine valves including components such as an external housing having an actuator including a valve for engaging a valve stem of the canister, a button trigger for activation of the valve and valve stem by a user, and a trigger return spring, to bias the button trigger out of engagement with the valve, an outlet for attachment to a flexible delivery conduit having a support wire guide, where the delivery conduit is wrapped around the external housing during storage, and during operation by a single individual user extends for a length from the vehicle driver seat through an open window or door, under the open hood for engagement with the vehicle engine intake manifold supported on a delivery conduit support clip, to enable one handed operation of the system by a single user.

Abstract: Dispenser [20] and system [100] providing a surface treatment to metal parts, equipment and vehicles for corrosion prevention. The dispenser [20] has an external housing [22] with an actuator [40], a valve for engaging a valve stem [V] of a canister, a button trigger [28] for activation, and a trigger return spring, to bias the button trigger [28] out of engagement with the valve. An outlet [26] from the external housing [22] enables removable attachment of a reusable flexible elongate delivery conduit [60] having a support wire [62]. Delivery conduit is stored wrapped around the external housing, and extends for between at least 2 and 3 feet for use. A fluid delivery end [68] of the delivery conduit includes a delivery nozzle [80] enabling a user to provide a spray pattern for fluid delivery, where the spray pattern dispenses fluid at a 45° angle with respect to the delivery conduit.

Abstract: An actuator for a spray can. The actuator includes a housing for attachment to an aerosol can covering a stem valve. A finger operating button structure is engaged with the housing for engaging the stem valve. A rotary two-way diverter valve is supported within the housing and rotatably engaged with the finger operating button structure. In a spray position/straw down, the two-way diverter valve directs spray through a first direct spray nozzle. In a second straw position/straw up, to make use of an adjustable straw, the diverter valve is rotated to engage a straw spray passage of the diverter valve in fluid communication with an adjustable rotary spray tip and engaged straw. By rotating the adjustable rotary spray tip to an aligned position, the tip substantially blocks the straw spray passage to provide a drip mode, where drops of fluid exit the straw. A flexible tip may optionally be provided on the straw to enable bending and retention of the flexible tip to a desired position.
