A method to extend the downstream and upstream data carrying capability of an HFC CATV system. At the neighborhood level, the CATV cable (the primary channel) is divided into different segments connected by electrically active junctions. At the junctions, each segment is also connected to a secondary data channel, such as an optical fiber or ultrahigh RF frequency (1 GHz+) secondary channel, which can carry supplemental downstream narrowcast channels and upstream channels between a plurality of such CATV cable segments. At the junctions, some CATV primary channel RF signals such as broadcast channels are passed without interference, while certain primary channel downstream narrowcast RF channels and upstream narrowcast RF channels are precisely suppressed using adaptive cancelling methods. Such adaptive cancellation methods are superior to prior art lowpass, highpass, and bandpass filtering methods because they allow for more efficient use of limited CATV primary channel RF spectrum.

A present invention is advantageously applied to a purge valve for purging evaporated fuel stored in a canister to an intake pipe of an engine. The purge valve has a fluid passage connecting an inlet port and an outlet port, and a normally closed valve port that is selectively opened by operation of an electromagnetic actuator is disposed in the fluid passage. A barrier pillar is disposed in the fluid passage between the inlet port and the valve port to suppress transmission of pulsating waves generated in the purge valve to the canister. Flow resistance of the barrier pillar is higher in a reverse flow direction from the valve port to the inlet port than in a normal flow direction from the inlet port to the valve port. The transmission of the pulsating waves is well suppressed by the barrier pillar while allowing a smooth flow from the canister into the purge valve.
