Abstract:
It refers to a door closing device (10) for an automatic closing of a door leaf (B) coupled with a floor and/or a doorpost (S) so as to swing. The door closing device (10) comprises a fixed unit (12) that is fixed on the floor and/or the doorpost (S), a translating unit (14) and a rotating unit (16) on which the door leaf (B) is fixed. The coupling of the three units (12, 14, 16) and the presence of elastic means (38) are such that, when the rotating unit (16) rotates in a first sense of rotation, the translating unit (14) is caused to translate in a direction and such that, when the translating unit (14) translates in an opposite direction, the rotating unit (16) is caused to rotate in an opposite sense of rotation.
Abstract:
Die Erfindung betrifft ein Schieberventil mit einem Ventilkörper (1) und einem an dem Ventilkörper (1) gelagerten Drosselkörper (2). Um ein Schieberventil bereitzustellen, das auch bei einem geringeren Fertigungsaufwand eine gute Dichtigkeit gewährleistet und deshalb preiswerter hergestellt werden kann, ist erfindungsgemäss vorgesehen, dass der Drosselkörper (2) mit einem in seiner Axialrichtung verlaufenden Schlitz (3) versehen ist.
Abstract:
Die Erfindung betrifft ein Regulierventil für Türschliesser und hydraulische Drehflügelantriebe mit einer Verstellschraube (1) und einer damit verbundenen Ventilhülse (2). Um ein Regulierventil der eingangs erläuterten Art zu schaffen, das Fluchtungsfehler zwischen der Mittelachse des Verstellgewindes und der Mittelachse des Führungsbereiches ausgleichen kann, das weiterhin eine Verdrehung der Ventilhülse (2) verhindert und das durch einen modularen Aufbau mit wenig Aufwand an entsprechende Einsatzbedingungen angepasst werden kann, ist erfindungsgemäss vorgesehen, dass die Verstellschraube (1) und die Ventilhülse (2) über eine Schnappverbindung (14) miteinander verbunden sind.
Abstract:
PROBLEM TO BE SOLVED: To provide a moving part, especially an actuating system for a cover which makes mandatory the intermediate position of the cover without current, causing abandonment of a costly gear device. SOLUTION: A piston on a piston rod divides a cylinder into two operation spaces. A base part 1 has an externally energy controlled drive device 17 that stands in operative connection with the moving part and functions in opposition to the operating force of a piston-cylinder device 7. A control system 29 monitors the motion of the actuating system 15, and identifies an obstacle when a parameter representing the motion of a stored parameter deviates from a threshold limit. A moving structure is held by a blocking device in an unpowered state of the actuating system, and the blocking device is formed by the piston-cylinder device 7. The actuating system 15 can block a flow connection 63 between the operation spaces 59, 61 via switching valves 55, 77, 97. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
A hinge device in which breakage of a structuring part caused by an increase in an internal pressure occurring in overloading is prevented. In the hinge device, a second member is adapted to be rotatable relative to a first member. A case (11) is fixed to either the first member or the second member, and a shaft body (12) capable of rotating relative to the case (11) is fixed to the other. A first chamber (14a) and a second chamber that are formed between the case (11) and the shaft body (12) are filled with viscous fluid. Between the first and second chambers (14a) is provided an orifice for narrowing a flow path in which the viscous fluid moves from the first chamber (14a) to the second chamber. The orifice enables the viscous fluid to resist rotation of the shaft body (12). A space region (26) is provided in the shaft body (12), and a valve body (28) is movably placed in the space region (26). When the pressure of the first chamber (14a) reaches a predetermined level, the valve body (28) moves in the space region (26) to increase the volume of the first chamber (14a).
