摘要:
A combined fuel cell and combustion tool including a combustion tool configured for receiving a fuel cell; the fuel cell having a housing defining an open end enclosed by a closure; a main valve stem having an outlet, disposed in operational relationship to the open end and reciprocating relative to the housing at least between a closed position wherein the stem is relatively extended, and an open position wherein the stem is relatively retracted; a fuel metering valve located within the housing, associated with the main valve stem, including a fuel metering chamber defined in part by a metering chamber seal and configured so that when the stem is in the open position, only a measured amount of fuel is dispensed through the outlet, the stem having a radially variable exterior contour periodically sealingly engaging the seal such that in the closed position a non-sealing relationship is defined between the stem and the seal, and in the open position a sealing relationship is defined between the stem and the seal; and the housing includes a separate fuel container, and the fuel metering valve includes a valve body that has a second end opposite the fuel metering chamber and located within the container, wherein the flow of fluid out the outlet of the fuel cell is solely from the separate fuel container.

A fuel cell for use with a combustion tool for delivery of a predetermined amount of fuel with each stem actuation is provided and includes a housing defining an open end enclosed by a closure. A main valve stem has an outlet, disposed in operational relationship to the open end and reciprocating relative to the housing at least between a closed position wherein the stem is relatively extended, and an open position wherein the stem is relatively retracted. A fuel metering valve is located within the housing, associated with the main valve stem, including a fuel metering chamber disposed in close proximity to the closure and configured so that when the stem is in the open position, only a measured amount of fuel is dispensed through the outlet. In a preferred embodiment, the fuel cell housing includes a separate fuel container, and the fuel metering valve includes a valve body having a second end opposite the fuel metering chamber located within the container.

摘要:
Assembly (10) consisting of a dispensing valve (11) for dispensing pressurised fluids, and a pouch (12) of flexible film material in fluid-tight connection therewith, which is placeable in an outer container (15) through an opening (14) therein that is sealable by a cover (13), the dispensing valve (11) having a valve body (18) which is mountable fluid-tightly at the edge (16) of a cover opening (17) formed in the container cover (13), to which valve body (18) an outlet tube (20) extending through a pouch opening (19) is able to make fluid-tight connection. The outlet tube (20) has a disc-shaped, especially cylindrical-cap-shaped, widened portion (21) extending around the pouch opening (19) inside the pouch (12). The pouch (12) is supported against the widened portion (21) of the outlet tube (20), with the intermediate arrangement of an annular disc (22) that bounds the pouch opening (19).

摘要:
A dispensing module for use in the dispensing of pressurized liquids, foams, gels or the like comprises the combination of a dispenser valve (12) and a flexible bag (24) which is bonded thereto. The bag (24) is intended to be located within an outer container (22) by way of an opening (23) in the latter that can be closed with a lid (25). Disposed within the bag (24) is a delivery nozzle (58) that can be connected to the valve body (14) of the dispenser valve (12) through the bag material with the interposition of a sealing ring (32) in such a way that between the interior (52) of the bag and the valve body (14) fluid communication is maintained. The delivery nozzle (58) and/or the valve body (14) is made of a material that is fracture-proof and in particular not permeable to organic media. The portion (34) of the delivery nozzle (58) immediately adjacent to the bag (24) is provided with a surface or a covering (36) of a material, such as polyethylene, polypropylene or polyamide, which can be bonded to the bag material.
摘要:
A precompression pump for spraying a liquid comprises a pumping chamber (502) containing a first piston (507) associated with an operating member (506), this piston bearing against a first spring (509); a precompression chamber (505) equipped with a second piston (510) bearing against a second spring (511), the precompression chamber communicating with the pumping chamber via a passage (550), so that their axes of symmetry being offset. A feed channel (504) equipped with a valve (504a, 515) emerges in the pumping chamber. A dispensing element (517) is equipped with a nozzle (520) and with a dispensing channel (518) connecting the nozzle to the precompression chamber, the latter including a device (F) for placing in communication and for closing the said passage (550), so that communication is interrupted in the position of rest of the pump and so that communication is established under the action of the operating member.
