Patent number: 6112950Abstract: A valve device is provided for being mounted in the neck opening of a receptacle containing a substance to be dispensed. The device includes a valve body (1) having therein a chamber (2) defined axially at one end by an annular valve gasket (3) including a central opening, and a valve plunger (10) passing through the gasket (3) and including a dispensing channel (12) opening out in its outside surface via a radial hole (13). The valve plunger (10) is molded out of a material which includes a mixture of acetal resin, polytetrafluoroethylene (PTFE), and silicone, so that the valve plunger (10) slides with low friction over the valve gasket (3).Type: GrantFiled: February 22, 1999Date of Patent: September 5, 2000Assignee: Glaxo Group LimitedInventors: Patrick Di Giovanni, Geralt Williams

Patent number: 5169038Abstract: A metering valve having a metering chamber (7) and a valve rod (2) lying in a valve body (1). The valve rod includes an inlet channel (211, 214) which puts the metering chamber (207) into communication with a can (11) of substance under pressure when the valve rod is in a rest position. The inlet channel forms a siphon which prevents the valve from draining when it is the rightway up.Type: GrantFiled: February 4, 1992Date of Patent: December 8, 1992Assignee: Valois (Societe Anonyme)Inventor: Patrick Di Giovanni

Patent number: 4966535Abstract: Some precompression pumps currently used for spraying a liquid include a non-return valve formed by a gasket (3) held captive between the base of the pump body (1) and a sleeve (2). This non-return valve determines the extent to which the pump chamber (19) is isolated from or put into communication with a supply of liquid, as a function of whether the gasket (3) bears against the base of the pump body (1) or against the sleeve (2), closing a central hole through the pump body or being held off a central hole through the sleeve.Type: GrantFiled: January 5, 1990Date of Patent: October 30, 1990Assignee: ValoisInventors: Jean-Pierre Lina, Patrick Di Giovanni

Patent number: 4930999Abstract: A precompression metering pump of the prior art which is otherwise particularly advantageous, is nevertheless difficult to prime because of the high degree of compressibility of the air it initially contains in its pump chamber. The present invention improves this aspect of metering pump operations. It consists in providing additional resilient means (20) and at least one cylindrical part (10) level with the conventional outlet non-return valve of the pump and constituting a second outlet non-return valve. In a particular embodiment, the resilient means and the cylindrical part are received one above the other in the outlet channel (33) of the pump actuator rod (31). To do this, they bear respectively against a choking step (32) in the form of a lug and a shoulder (34) presented by said channel. In normal operation, the differential piston (4) of the pump moves out of the way so that operation takes place as in a prior art precompression metering pump.Type: GrantFiled: June 2, 1989Date of Patent: June 5, 1990Assignee: Societe Technique de Pulverisation - STEP SAInventors: Michel Brunet, Patrick Di Giovanni, Claude Jouillat, Jean-Pierre Lina, Herve Pennaneac'h
