Claim Text:
1. A pressure spike reducing apparatus comprising: a housing connectable at each end to a pipe or hose through which fluid may flow, the housing having a fluid channel to permit the flow of fluid from the pipe or hose at one end of the housing through to the pipe or hose at the other end of the housing; a piston disposed within the housing and around the fluid channel; and a closed pressurized gas chamber disposed within the housing and around the fluid channel on a downstream side of the piston; a first fitting disposed at the upstream end of the housing and a second fitting disposed at the downstream end of the housing, each fitting comprising a neck extending outwardly from the housing that is engageable with the pipe or hose; wherein the closed pressurized gas chamber is configured to hold the piston in a first upstream position until a pressure spike in the pipe or hose occurs; and wherein when a pressure spike occurs, the pressure causes the piston to move to a second downstream position to create a fluid chamber within the housing.
