摘要:
A damped liquid spring construction in which high instantaneous pressure rises are damped so as not to be experienced at the seal including a cylinder containing compressible liquid with a piston in the cylinder and a seal located in sealing engagement with the piston, and an annular pressure damping ring mounted in contiguous relationship to the seal, the pressure damping ring including an annular surface spaced from the outside surface of the piston for providing an annular space around the piston for restricting transmission of pressure and shock pulses from the main portion of the cylinder to the portion at which the seal is located, to thereby damp high substantially instantaneous pressure rises before the high pressure can affect the seal.
