Abstract: A gasoline vapor treating system includes a single hydrocarbon filter apparatus interconnected to a fuel tank having a range of vapor pressures therein, said filter apparatus receiving hydrocarbon vapors from said tank for one vapor pressure in said fuel tank and said filter apparatus delivering air and hydrocarbon vapor to said tank from said filter responsive to another vapor pressure in said tank lower than said one vapor pressure, said filter operated serially between hydrocarbon loading and hydrocarbon unloading cycles without reference to any other hydrocarbon removal apparatus. A balance nozzle includes a mechanism to mechanically operate a vapor valve therein before the fuel valve is opened.

Abstract: A nozzle for dispensing fluid including a nozzle body having a fluid path which is configured to receive fluid therein and a vapor path which is configured to receive vapor therein. The nozzle further includes a main fluid valve positioned in the fluid path to control a flow of fluid therethrough, the main fluid valve including a main fluid valve spring configured to bias the main fluid valve to one of its open or closed positions. The nozzle further has a main vapor valve positioned in the vapor path to control a flow of vapor therethrough. The main vapor valve includes a main vapor valve spring configured to bias the main vapor valve to one of its open or closed positions. At least part of the main fluid valve spring or the main vapor valve spring is positioned within the other one.

Abstract: A nozzle system including a nozzle body configured to dispense fuel through a fuel path thereof into a vehicle tank. The nozzle body includes a vapor path configured such that vapor recovered from the vehicle tank during refueling is passable therethrough. The nozzle system further includes a main vapor valve positioned in the vapor path and configured to selectively block the vapor path. The main vapor valve is movable to a position wherein the main vapor valve does not block the vapor path. The nozzle system further includes a relief valve in fluid communication with the vapor path. The relief valve is configured to open to allow ambient air to enter into the vapor path when sufficiently low pressure is present in the vapor path, and the relief valve is generally aligned with the main vapor valve.

Abstract: Spout assemblies are provided for dispensing liquid from a nozzle.

Abstract: A nozzle is provided for dispensing liquid into a container. The nozzle includes a nozzle body, having an inlet for receiving liquid, an outlet for dispensing liquid, and a liquid passage extending between the inlet and the outlet. A poppet valve assembly including a poppet valve stem, wherein the poppet valve assembly is adapted to selectively control the flow of liquid through the liquid passage. A latch stem is provided that is slidable to and from an operative position. A retention pin attached to the latch stem and at least one first rotatable member is disposed to contact the retention pin. A first lever portion includes at least one second rotatable member disposed to contact the poppet valve stem and a second lever portion. The second lever portion has a first end pivotally attached to the first lever portion and a second end that engages at least one of the retention pin and first rotatable member.

Abstract: A nozzle is provided including with a nozzle body having an inlet for receiving liquid, an outlet for dispensing liquid, and a liquid passage extending between the inlet and the outlet. The nozzle includes a valve assembly adapted to selectively control the flow of liquid through the liquid passage. The nozzle further includes a latch stem including a latch groove and a pivot and a lever pivotally attached to the latch stem adjacent the pivot, wherein the latch stem may be selectively locked with respect to the nozzle body to provide an operable pivot to facilitate actuation of the valve assembly by the lever, and wherein the latch stem may be selectively unlocked with respect to the nozzle body to release the pivot to hinder actuation of the valve assembly by the lever.

Abstract: Dispensing nozzles having a spout for dispensing a fluid are provided. The spout comprises a first tube for engaging the dispensing nozzle and having an outer surface, a proximal end, a distal end, and a first passage interconnecting the proximal and distal ends. A second tube is disposed within the first passage of the first tube and communicates with a first opening on the outer surface of the first tube, the first opening being located adjacent the distal end. A valve seat is disposed at least partially within the first passage at the proximal end of the first tube and has a second passage disposed therein. A plug is disposed within the first passage between the valve seat and the distal end and has a third passage extending therethrough. A valve is disposed between the plug and the valve seat for sealingly engaging the valve seat, the valve being biased into engagement with the valve seat.

Abstract: A sanitary pressure regulator comprises a pressure sensing chamber, downstream of an orifice, has its upper portion defined by a diaphragm. A valve stem, mounted on the diaphragm, extends downwardly through the orifice and has a plug disposed on the upstream side of the orifice. A valve spring, is disposed in a spring housing and acts through a lower spring retainer to yieldingly resist movement of the valve plug to a position which would restrict fluid flow. The spring housing, compression spring and lower retainer form a unit which can be mounted on and detached from a passage housing. The valve stem is mounted on the diaphragm by a nut which is threaded onto a portion of the stem which projects above the diaphragm. Provision is made to lock the valve stem in an open position to facilitate the use of high pressure fluid in cleaning the regulator. In an alternate embodiment, the valve stem is axially fixed relative to the lower spring retainer and a disc engages the lower surface of the diaphragm.
