Abstract
Abstract A low speed air bleed absorption reduction oil saving device for carburetor characterized in the ability to turn air valve to open automatically in circumstances where the automobile concerned is reducing its speed, going downhill or the carburetor is experiencing a momentous absorption internally such that the rotation speed of the engine remains above 950 RPM, equivalent to a speed in motion that is higher than 25 Kms per hour as executed by the high-speed gear, so as to enable the air to enter the cylinder via the air filter so as to hold down the vacuum absorption so as to prevent overfilling of gasoline into the cylinder thereby achieving the objective of saving of use of gasoline fuels.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
245 words
A low-speed air bleed absorption reducer fuel-saving device for connection to the fuel intake tube and the valve of a carburetor for use to save fuel fed to the engine of a land vehicle when the land vehicle to which it is connected is travelling downhill, changing from a lower speed to a higher speed by virtue of gear shifting, or on the point of executing a braking action, the fuel saving device comprising an air intake control mechanism having a connection to an air purifier, an air intake bypass porthole connected to said intake control mechanism, a low speed fuel network connected to said bypass porthole and to the engine of the land vehicle to feed the cylinders of the engine, said air-intake control mechanism including a valve gate to block and unblock said air intake bypass porthole from said connection to the air purifier, said airtake control mechanism having a connection to the fuel intake tube of the carburetor and to a throttle valve of the carburetor and means connected to said valve gate to automatically move said valve gate between blocking and unblocking positions, with vacuum in the fuel intake tube when the throttle valve is closed moving said means and said valve gate to an unblocking position allowing air from said connection to the air purifier into said air intake contol mechanism to said bypass porthole into said low-speed fuel network to feed the air to the cylinders of the engines.
Claim 2
Dependent Claim
245 words
A low-speed air bleed absorption reducer fuel-saving device for connection to the fuel intake tube and the valve of a carburetor for use to save fuel fed to the engine of a land vehicle when the land vehicle to which it is connected is travelling downhill, changing from a lower speed to a higher speed by virtue of gear shifting, or on the point of executing a braking action, the fuel saving device comprising an air intake control mechanism having a connection to an air purifier, an air intake bypass porthole connected to said intake control mechanism, a low speed fuel network connected to said bypass porthole and to the engine of the land vehicle to feed the cylinders of the engine, said air-intake control mechanism including a valve gate to block and unblock said air intake bypass porthole from said connection to the air purifier, said airtake control mechanism having a connection to the fuel intake tube of the carburetor and to a throttle valve of the carburetor and means connected to said valve gate to automatically move said valve gate between blocking and unblocking positions, with vacuum in the fuel intake tube when the throttle valve is closed moving said means and said valve gate to an unblocking position allowing air from said connection to the air purifier into said air intake contol mechanism to said bypass porthole into said low-speed fuel network to feed the air to the cylinders of the engines.
Claim 3
Dependent Claim
137 words
The fuel saving device of claim 1, further characterized by said air intake control mechanism further including a base lid, said connection to the fuel intake tube of the carburetor including an extensible tubing connecting said base lid to the fuel intake tube, a top lid enwrapping over said base lid, a chamber annexed onto said top lid and having intake and exit aisles into and out of said chamber, said means to automatically move said valve gate including a film piece fixed between sad base lid and said top lid, said valve gate including a plug means fixed unto said film piece to control access to said exit aisle, adjustable spring means to adjust the thrust of said plug means to allow said plug means to have sufficient thrust force to seal closed said exit aisle.
Claim 4
Dependent Claim
72 words
The fuel saving device of claim 2, further characterized by said adjustable spring means including a pipe joint screw-matched to said extensible tubing and having a passage therethrough for connection to the fuel intake tube of the carburetor, and a spring connected between said pipe joint and said film piece for adjustment by movement of said pipe joint to regulate elasticity of said spring between said pipe joint and said film piece.
