Abstract:
1. An engine system comprising: an engine, a pressure regulator coupled to said engine, and including a container having a chamber formed therein, and having an opening formed therein and communicating with said chamber thereof, for pressure relieving purposes, and a needle tube mechanism disposed in said chamber of said container and including a block coupled to said engine with a pipe, to receive gas from said engine, said block includes a slit formed therein and connected to said pipe and includes a channel formed therein and communicating with said slit thereof and communicating with said chamber of said container, said slit of said block including an inner diameter smaller than that of said channel of said block, said slit and said channel of said block being arranged to allow the gas from said engine to flow into said pipe and then to flow through said slit of said block, and then to flow through said channel of said block, and then into said chamber of said container when said engine is over-pressurized, and said slit and said channel of said block being arranged to allow the gas in said chamber of said container to flow into said channel of said block, and then to flow through said slit of said block, and then to flow into said engine via said pipe, in order to balance a pressure in said engine when the pressure in said engine is too low.
