A liquid pressure pulsation damper has a body, the inlet and outlet branch pipes, central tube that is placed in the body, partition installed normally to the axis of central tube, this separates the body and the central tube into parts, continuous flow cavities formed with the body, central tube and the partition, openings provided in the central tube and connecting the central tube with continuous flow cavities formed by the central tube and the body, narrowed branch pipes that connect to each other the continuous flow cavities formed by the central tube, the body and the partition, elastic blocks arranged as silphons or placed with the smaller step in one of silphons and installed in the central tube at both sides of the partition, at that in the central tube at the side of the basis of the silphons, out of its crimps, rings are placed, inner diameter of those is smaller compared to the outer diameter of the silphon, and distance between those and the first crimps of silphons is larger compared to the maximal working stroke of the crimp of silphon, and the openings provided in the central tube that connect the central tube to continuous flow cavities formed by the central tube and the body are placed between the partition and the rings. |
