Kimmo Timonen and Andreas Nodl also scored for the Flyers, who have won three straight since a lackluster 2-1 loss to Columbus on Oct. 25 that angered the players. The slumping Islanders dropped their fourth in a row after a three-game winning streak.
Philadelphia has dominated the Islanders during the past three seasons, and continued that trend in their first meeting of this season. Philadelphia has won 15 of 16 from New York, including 11 straight at home. The Islanders haven't won in Philadelphia since April 7, 2007.
In front of many fans dressed in orange-and-black Halloween costumes, Timonen gave the Flyers a 1-0 lead 2:36 into the game. Scott Hartnell angled a pass from the side of the net to Timonen, who fired in a shot off of goalie Rick DiPietro's stick.
Carter made it 2-0 with 2:41 left in the first period, deflecting Claude Giroux's pass between DiPietro's pads. Carter's second goal early in the second period gave him five this season, one behind team leader Danny Briere. Carter led the Flyers with 33 goals last season.
Carter nearly had a hat trick, but DiPietro deflected away his attempt.
Pronger's first two goals of the season both came on one-timers off smooth passes from Timonen. The hard drives both sailed high and over DiPietro's shoulders.
Between his goals, Pronger was called for hooking Frans Nielsen on a breakaway, resulting in a penalty shot. Nielsen skated in, transferred the puck to his backhand and flipped it over Bobrovsky's left shoulder.
Not allowing that to lead to any momentum for the Islanders, Andreas Nodl beat DiPietro after a centering pass from the left circle by James van Riemsdyk.
Bobrovsky (5-2), playing in his seventh game, stopped 30 shots.
Tempers flared with one minute left in the game, and DiPietro, Nielsen, Briere and Dan Carcillo scuffled in a flurry of activity. Order was eventually restored, and 19 minutes of penalties were handed out.
Notes: Flyers G Michael Leighton (back surgery) said he felt well after skating with the team for the first time since Oct. 11. He was expected to return around Nov. 22, but Leighton is hoping to be back sooner. ... Islanders RW Michael Grabner missed his second straight game because of a groin injury.
