摘要:
A pressurized writing device comprising an ink tube (12) having a first end (18) and second end (20), a writing tip (22) at the first end, an end plug (30) at the second end and a pressurizing system (24). The pressurizing system applies a force to a writing medium (14) in the ink tube to force the writing medium out the writing tip. The pressurization system includes a compressible ink driving member (28). The compressibility of the ink-driving member assures a secure seal of the writing medium in the ink tube. Additionally, the compressibility permits the ink-driving member to wipe ink off the interior surface of the link tube as ink is expended.
摘要:
The invention relates to a device for the application of a flowable medium, notably a tissue adhesive, comprising at least one reservoir (16) for the medium which presents an outlet (22) from which the medium exits when the medium and/or the reservoir (16) are subjected to pressure. A pressure-generating element (20) acts on the medium and/or the reservoir (16) and is preloaded by means of a preload device (34). Said preload device (34) can be blocked by means of a controllable blocking device (58) which presents a mobile fixing element (54) which in at least one fixing position immobilizes the preload device (34) against movements induced by preloading and for releasing said preload device (34) can be moved out of the at least one fixing position. The invention also provides for a release device (81) for the targeted releasing of the blocking device (58). The release device (81) comprises a release element (82) for temporarily displacing the fixing element (56) from its at least one fixing position.

Um den möglichst vollständigen Ausstoß des plastischen Inhaltes eines Spritzbehälters zu erreichen, welcher an seinem freien Ende einen im wesentlichen kreiszylindrischen über eine Wand (6) des Behälters (1) vorstehenden Anschlußstutzen aufweist, an dem eine Spritzdüse (20) befestigbar ist, über die das im Behälter (1) enthaltene Material ausgegeben werden kann, weist die Spritzdüse (20) ein Rohrstück (28) auf, das bei montierter Spritzdüse in den Anschlußstutzen (2) hineinragt und dessen Außendurchmesser in dem in den Anschlußsstutzen (2) hineinragenden Teil (36) des Rohrstücks (28) im wesentlichen gleich dem Innendurchmesser des Anschlußstutzens ist.

摘要:
Manually operated dispensing apparatus for pasty substances, in particular silicone, comprising a hollow vessel (2) provided with a rear loading opening through which the paste to be dispensed is introduced, a front paste dispensing spout (26), a manually operated dispensing actuation lever (3), a plunger element (7) displaceably located inside said hollow vessel, which is arranged to be closed on its rear side by a sealing element (6), said dispensing actuation lever (3) being formed by two segments (3a, 3b) arranged at an angle with respect to each other. An elastically deformable air chamber (4) is pressed by the actuation of said lever (3) so as to cause its volume to be reduced and the air contained in said air chamber to be injected under pressure, through an aperture (20) in the wall of the sealing element (6) and a double check valve (5), into the cavity formed between the rear sealing element (6) and the plunger element (7). The air chamber is an elastically deformable concave air chamber with a substantially circular shape, and is applied in a tightly sealed way on to the outer surface (10) of said sealing element.
摘要:
A pneumatic controller for a dispenser for viscous materials has a pistol grip body (50) in which is mounted a trigger (52) which is operably connected with regulated pressure setting member (16) of a pressure regulator (10) by a pair of linkages (56 and 60) pivotally connected to the trigger and the body. As the trigger is depressed the plunger adjusts the regulated pressure setting. This allows the rate at which the viscous material is dispensed to be adjusted by the hand holding the pistol grip.
