Pneumatic jack is fabricated model which installed on the four wheeler, which is used to solve the problem arising in the conventional jack. This fabricated model consist of small size reciprocating air compressor which is driven by the battery use in four wheeler and an air tank is use to jack store the compressed air, and a pneumatic control valve which regulate the air flow and double acting cylinder used as a jack which perform lifting. This jack is installed on the chassis using jack and the problem related to tyres such as puncture tyres, tyres replacement and wheel balancing can be resolved with less effort and time. Key words: Compressor, Chassis, Pneumatic Cylinder, Solenoid Valve, Control Circuit and Jack I. INTRODUCTION Our survey in the regard in several users of vehicles, revealed the facts that mostly some difficult methods were adopted in lifting the vehicle for reconditioning. Now the project is mainly concentrated on this difficulty, such that the vehicle can be. The lifted from the floor land without application of any impact force. The inbuilt pneumatic jack is a device used to elevate heavy weight without manpower. The operation is made simple so that even unskilled person can use it with ease. As automobile market is growing, advance concepts are being implemented to make automobile more and more versatile and comfortable. Many concepts are implemented day to day to make automobile better these days. In this way the becomes more versatile and can be operated over variety of bad as well as good road conditions. Here we are converting the rotary motion into linear motion for lifting the vehicle using the jack which is fixed at the bottom of the cassis. The motor is operated by the control unit. Is gets power form the battery. The two number of pneumatic jack is arranged under the vehicle body. Out of the one is connected vertically and other is horizontally. When we press the button in the control unit the motor starts rotates. Then the air is compress by using motor. This compress air is used to move the jack from its initial position to the working position. Then the shaft in the cylinder moves down by touches the ground and lifts the front or back wheels of the vehicle. the wheel are grounded safely even after the wheel puncture or any other fault in the vehicle. A. Pneumatics The “pneuma” is Greek word and it means wind. The word pneumatics is study of air movement. Pneumatics is used for carrying out the simplest mechanical tasks in more recent times. That has played a more important role in the development of pneumatic technology for automation. Pneumatics systems operate on the supply of compressed air which is must be made available in sufficient quantity and at a sufficient pressure to suit the capacity of the system. When the pneumatic system is being adopted for the very first time, it wills indeed the necessary to deal with the question arise in front of them that compressed air supply. The supply of compressed air is done by using reciprocating compressor. A compressor is a machine that takes in air at a certain pressure and delivered the air at a high pressure. Compressor capacity is the actual quantity of air compressed and delivered and the volume expressed is that of that the air at intake. The compressibility of the air was first introduced by Robot Boyle in 1962 and that found that the product of pressure and volumes of particular quantity of gas. The usual written as PV =C (or) Pi*Vi =P2*V2 In this equation the pressure is the absolute pressure. In general any gas can be used in pneumatic system but air is the mostly used. B.
