Abstract:
Pressure compensators (1) for stabilizing a flow of water are disclosed. The pressure compensator (1) includes water compensating channels (3) formed on the outer periphery of their body (2), and flow orifices (4) passing through the pressure compensator (1), so that the water compensating channels and the flow orifices control the flow rate of the water at varying pressures. The body of the pressure compensator (1) preferably comprises a flexible material, such as rubber.
