Pulsation damper for a hydraulic elevator |
摘要 |
A pulsation noise damper has an axially symmetrical housing (4) forming a chamber (3) in which pressurized hydraulic fluid flowing in an elevator system hydraulic line can expand. For the collection of contaminates in the hydraulic fluid a filter (6) is arranged at one of a pair of input/output openings (5) formed the housing (4). A pair of compression elements (7), each in the shape of an elastic bellows, are positioned in end openings (4a) formed in the housing (4) and the stiffness of each is selectively adjusted by a movable pressure plate (8) coupled to a fastening element (9). In this way the pulsation noise damper can be adapted to various levels of pulsation energy. The compression elements (7) are retained by end caps (1) attached to the housing by fasteners (2) and the fastening elements (9) extend through the end caps and are fixed by nuts (10).
