Abstract
(DE)
Um eine Druckerzeugungsvorrichtung (1) zum Erzeugen eines Hydraulikdruckes in Folge einer Zug- oder Druckbeanspruchung mit Anschlüssen (3), von denen einer mit einer Mechanik zum Einleiten einer mechanischen Zug- oder Druckbeanspruchung und ein anderer Anschluss (2, 3) starr mit einem Gestell verbindbar ist, einem Druckzylinder (12) und einer Kolbeneinheit (8), die sich zumindest teilweise und beweglich in dem Druckzylinder (12) erstreckt und gemeinsam mit dem Druckzylinder (12) eine mit Hydraulikflüssigkeit befüllte Hydraulikkammer (11) begrenzt bereitzustellen, die in ihrem Aufbau einfach und kostengünstig ist, wird vorgeschlagen dass, die Anschlüsse (2, 3) über Ankopplungsmittel (4, 7, 14, 17) mit dem Druckzylinder (12) oder der Kolbeneinheit (8) verbunden sind, wobei die Ankopplungsmittel (4, 7, 14, 17) so ausgestaltet sind, dass bei einer Zugbeanspruchung und bei einer Druckbeanspruchung dieselbe Hydraulikkammer (11) mit Druck beaufschlagt wird.
(EN)
The invention relates to a pressure generating device (1) for generating a hydraulic pressure as a result of a tensile or compressive load, having connections (3), one of which can be rigidly connected to a frame by means of a mechanism for introducing a mechanical tensile or compressive load, a pressure cylinder (12) and a piston unit (8) extending at least partially and flexibly in the pressure cylinder (12) and bounding a hydraulic chamber (11) filled with hydraulic fluid jointly with the pressure cylinder (12), said chamber being simple and inexpensive in construction, wherein the connections (2, 3) are connected to the pressure cylinder (12) or the piston unit (8) by means of coupling means (4, 7, 14, 17), wherein the coupling means (4, 7, 14, 17) are designed such that the same hydraulic chamber (11) has pressure applied thereto under tensile load and under compressive load.
(FR)
Afin de fournir une construction simple et économique pour un dispositif de production de pression (1) destiné à produire une pression hydraulique à la suite d'une sollicitation en traction ou en pression, avec des raccordements (3) dont l'un peut être relié à un élément mécanique pour appliquer une sollicitation mécanique en traction ou en pression tandis qu'un autre raccordement (2, 3) peut être relié de manière rigide à un châssis, avec un cylindre de pression (12) et une unité de piston (8) qui s'étend au moins partiellement, de manière mobile, dans le cylindre de pression (12) et qui forme avec le cylindre de pression (12) une chambre hydraulique (11) remplie d'un liquide hydraulique, il est proposé que les raccordements (2, 3) soient reliés par des moyens d'accouplement (4, 7, 14, 17) au cylindre de pression (12) ou à l'unité de piston (8), les moyens d'accouplement (4, 7, 14, 17) étant configurés de telle sorte que, lors d'une sollicitation en traction et lors d'une sollicitation en pression, la même chambre hydraulique (11) soit soumise à la pression.
