Patent CA-2473932-A1 (CA)
Title: Automatic valve
Inventor: SHANKLIN DONALD J
IPC: B65D83/40
Filed: 2003-01-22
Abstract: A dispenser can automatically dispense chemical from an aerosol container (22) at predetermined intervals without the use of electric power. A diaphragm (58) at least partially defines an accumulation chamber (56) that receives chemical from the can (22) during an accumulation phase. Once the internal pressure of the accumulation chamber (56) reaches a predetermined threshold, the diaphragm (58) moves, carring with it valving (33) that controls a spray burst. The diaphragm (58) assumes its original position when the pressure within the accumulation chamber (56) falls below a threshold pressure. A barrier prevents the aerosol container (22) from resuppling the accumulation chamber (56) at a high rate during the spray phase, preferably due to a porous gasket disposed in a passageway linking the dispenser to the aerosol container (22).

Patent CA-2507962-A1 (CA)
Inventor: CARPENTER TODD L
IPC: F02M25/08
Filed: 2005-05-18
Abstract: An evaporative emissions control system for small internal combustion engines.  The system generally includes a charcoal canister and a carburetor with a fuel circuit shutoff valve. The charcoal canister is in fluid communication with the air space above the liquid fuel within the engine fuel tank, and optionally, with the air space above the liquid fuel within the fuel bowl of a fuel bowl-type carburetor. The charcoal canister contains charcoal media which absorbs fuel vapors when the engine is not running. During running of the engine, vacuum within the carburetor induces a flow of atmospheric air through the charcoal canister to purge the collected fuel vapors from the charcoal media, and the fuel vapors pass into the engine for consumption. The carburetor of the engine, which may be either a fuel bowl-type carburetor or a diaphragm carburetor, includes a fuel circuit shutoff valve controlled either by a vacuum signal produced within the engine or by a user-actuated mechanical linkage. The fuel circuit shutoff valve closes the fuel circuit of the carburetor upon engine shutdown to prevent escape of fuel vapors from the carburetor to the atmosphere. In another embodiment, a weir-type carburetor is disclosed which contains a minimal amount of fuel when the engine is not running to reduce or eliminate evaporative emissions.
