摘要:
A cartridge 12 for pneumatic dispenser is provided that is configured by fitting a plunger 10 into a cylinder 18. The plunger 10 has a main body portion 80, and a seal 104 formed, when the plunger 10 is fitted in the cylinder 18, between an outer circumferential surface 82 of the plunger 10 and an inner circumferential surface 84 of the cylinder 18. The outer circumferential surface 82 that allows the plunger 10 to be fitted in the cylinder 18 in a fitted state forms a substantially-circumferential radial clearance via-a-via the inner circumferential surface 84, thereby forming a tubular clearance 106 continuously extending both axially and circumferentially between the outer circumferential surface 82 and the inner circumferential surface 84. When a viscous material 14 is filled to a filling chamber 72 from the outside, the clearance 106 is filled with a portion of the viscous material 14, thereby forming the seal 104.

Die Erfindung betrifft ein Auspressgerät (11) für Massen enthaltende Gebinde (46), das eine Auspressvorrichtung (12) und eine Kassette (32) für das Gebinde aufweist. Die Auspressvorrichtung (12) weist eine Auspresseinrichtung (13) und eine Aufnahme (23) für die Kassette (32) auf. Die Aufnahme (23) ist frontseitig von einer Kopfplatte (24) sowie rückseitig von einer Gehäusewand (20) der Auspresseinrichtung (13) begrenzt. Die Kassette (32) ist um eine von der Kopfplatte (24) zur Gehäusewand (20) verlaufenden Schwenkachse (27) schwenkbar an der Auspressvorrichtung (12) festgelegt und von einer Auspressstellung in eine Beladestellung überführbar. Weiter betrifft die Erfindung eine Auspressvorrichtung (12) für ein derartiges Auspressgerät (11) und eine Kassette (32) für ein derartiges Auspressgerät (11).
摘要:
A device (100) for mixing and dispensing a dental material from at least two components comprises for each component a hydraulic actuator (10,20). The hydraulic actuator (10,20) has at least three telescopically interacting thrust members (11,12,13) which are adapted to telescopically move relative to each other. The hydraulic actuator (10,20) is operated through relative movement of the thrust members (11,12,13), and may be used to advance a component of the dental material toward a dispensing outlet (112,113).
摘要:
A valve (36), in particular but not exclusively, for a pneumatic dispenser is provided, the dispenser (2) comprising a handle (14) with an actuation arrangement (18,20) for actuation by an operator holding the handle to selectively apply pressure to a respective one of the front (34) and rear (30) chambers on either side of a piston (28) coupled to a rod for applying a dispensing force, thereby controlling advance and retreat of the rod. The valve is provided with a body and first (56) and second (58) moveable members moveable relative to the body. The valve can be arranged as a space saving five port valve instead of two three port valves for use in the disclosed dispenser and can be arranged to provide a fail safe mechanism if both valve members are actuated concurrently. Additionally, a dispenser comprising a stock portion and a cylinder secured to the stock portion is disclosed. Pressure is supplied to the rear chamber of the cylinder from the stock portion through its front chamber and the piston moveable inside the cylinder.

A pneumatic dispenser for dispensing viscous material, for example, mastic caulk, from a container is described. The dispenser comprises a fluid supply arrangement for accepting a dispensing nozzle (76) of the container and providing a flow of pressurised fluid to the dispensing nozzle to enable the material to be dispensed as a spray. A moveable member (18) can be used to control the flow of pressurised fluid, for example a member disposed on a cap (14) for closing a container containing compartment of the dispenser and/or a moveable member (18) disposed around the dispensing nozzle (76). The arrangement of the fluid supply arrangement allows for convenient control of the pressurised fluid flow for spraying the material. Also disclosed is a dispenser with a readily exchangeable pressure application interface for applying a dispensing pressure to the container, enabling the dispenser to be used with both cartridge and foil pack containers.

Die Erfindung betrifft eine Austragsvorrichtung für Kartuschen umfassend einen Abzugsgriff zum Bedienen eines Ventils der Austragsvoffichtung, einen Anschluss zum Einspeisen eines unter Druck stehenden Gases, ein Kartuschenanschlussstück zum Anschließen einer Kartusche und einen Grundkörper, in dem wenigstens ein Durchgang verläuft, durch den das unter Druck stehende Gas zum Kartuschenanschlussstück leitbar ist, wobei das Kartuschenanschlussstück eine Öffnung zu dem Durchgang umfasst, so dass bei Beaufschlagung eines Bodens einer im Kartuschenanschlussstück angeordneten Kartusche mit dem unter Druck stehenden Gas, der Inhalt aus der Kartusche austreibbar ist, und wobei der Durchgang durch das bedienbare Ventil schließbar und zu öffnen ist, wobei das Ventil ein Ventilkörper ist, der drehbar im Grundkörper angeordnet ist, wobei eine Bewegung des Abzugsgriffs zu einer Drehung des Ventilkörpers im Grundkörper führt und der Durchgang im oder am Ventilkörper angeordnet ist, so dass in einer ersten Position des Ventilkörpers der Durchgang geschlossen ist und in einer zweiten Position des Ventilkörpers der Durchgang im oder am Ventilkörper das unter Druck stehende Gas zu dem Kartuschenanschlussstück leitet.
摘要:
A nozzle (20) is used in a hand held dispenser of viscous fluid including caulking, sealant or adhesive. The nozzle (20) has an elongated body that extends along a longitudinal axis, defining a fluid path extending between a dispensing end (21) and a base (32). The base includes a coupling (30) to secure the nozzle (20) to a dispensing device or to a container (10) of the viscous fluid. The nozzle (20) includes a variable flow valve (26) that operates through a range of positions, between a fully closed position and a fully open position. The valve (26) operates within a housing (27) that extends across the longitudinal axis of the body. A second coupling (28) connects the valve (26) to a hand control on the dispenser. Preferably, the valve (26) rotates between the closed and open positions. The nozzle (20) is also included in a dispensing gun. The dispensing gun includes a hand activated control on the gun handle. The control operates the valve (26) between the closed and open positions and co-acts to urge the fluid contents of the dispensing gun to flow through the nozzle (20). A kit for a nozzle assembly in a hand held dispenser includes the nozzle (20) and a replaceable nozzle tip (23). The kit may also include one or more interchangeable nozzle tips (23), a replaceable end cap (305), and a cleaning tool (100) for the nozzle.
