A hydraulic damping cylinder, in particular for a prosthetic knee joint, comprising a housing, a cylinder chamber which is provided in the housing and which is filled with a hydraulic fluid, and a piston which is arranged in said cylinder chamber and which can be moved in the cylinder chamber by way of a piston rod which is introduced into the cylinder chamber, wherein, in the housing (2), there are provided at least two separate receiving chambers (17, 21), which are of different size and are connected to the cylinder chamber (3) by way of fluid ducts, for hydraulic fluid displaced from the cylinder chamber (3) during a piston movement, which receiving chambers are in each case separated, by way of a diaphragm (19, 24), from a compression chamber (20, 23) filled with a compressible fluid that forms an energy store, wherein, upstream of the relatively large receiving chamber (17), there is connected a throttle device (27) which forms a flow resistance for the hydraulic fluid flowing into the receiving chamber (17), in such a way that the hydraulic fluid can be distributed to the two receiving chambers (17, 21) in a manner dependent on the speed of the piston movement.一種特別是用於人工膝關節的液壓阻尼筒包括外殼、設置在該外殼內並以液壓流體填充的汽缸室、以及設置在該汽缸室內的活塞，該活塞經由被導入該汽缸室的活塞桿而在該汽缸室內移動，其特徵在於，在該殼體(2)內，設置有至少兩個分離的接收室(17、21)，該接收室有不同尺寸，並且經由流體導管被連接到該汽缸室(3)，在活塞移動期間，接收從汽缸室(3)移出的液壓流體，接收室經由隔膜(19、24)而與壓縮腔(20、23)分隔，該壓縮腔以可壓縮流體填充，以形成能量存儲，其中，該相對較大接收室(17)的上游連接有節流閥裝置(27)，該節流閥裝置對流入接收室(17)的液壓流體形成流動阻力，以這樣的方式，取決於該活塞移動的速度，該液壓流體可以被分配到該兩個接收室(17、21)。
