  "textContent": "A gas shock absorber has a pressure tube (30) which defines a working chamber (42). A piston (32) divides the working chamber into an upper working chamber (44) and a lower working chamber (46). A flow path (70,72) extends through the piston to provide fluid communication between the upper and lower working chambers. A valve body (150) is attached to the pressure tube. The valve body defines a flow path between the working chamber and a fluid chamber (150,350,550). The fluid chamber is in communication with either the upper working chamber or the lower working chamber. The fluid chamber can be defined within the pressure tube, between the pressure tube and a chamber tube (238) or it can be defined by an air spring assembly.",
