Air motor

The utility model relates to engine building and the conversion of compressed air energy in air motor cavities to mechanical energy without harmful environmental consequences.

A device is known that is used as an air motor, comprising a cylinder with a piston, a gas distribution system with intake and exhaust valves, comprising exhaust windows at the bottom of the cylinder. (RU # 2206791C1, 06/20/2003)

The disadvantage of this device is that the return stroke of the piston is due to the source of external mechanical force.

Known air motor containing a chamber divided by a piston into two working cavities, a piston with a crank mechanism. The disadvantages of this air motor are the design complexity, the use of expensive refrigerant, the dependence of the air motor on the ambient temperature, which reduces the efficiency of the air motor.

The task set in this utility model is to increase the efficiency of the air motor and simplify the design.

The task is achieved by the fact that the known air motor. comprising a chamber divided by a piston into two working cavities, a piston with a crank mechanism, according to the invention, comprises a pneumatic distribution device connected through an air-controlled unit to a high pressure line, each chamber cavity is connected by a separate line for pumping and discharging the working fluid with a pneumatic a switchgear connected to an electromechanical converter connected to a master oscillator.

The invention is illustrated in the drawing, where

- figure 1 presents a diagram of an air motor;

- figure 2 presents a timing diagram of the operation of the air motor.

The air motor contains a chamber 1, divided by a piston into two working cavities 2 and 3, a piston 4, its rod 5 is connected through a connecting rod 6 and a crank 7 to a crank mechanism 8. Each cavity 2 and 3 of the chamber 1 is connected by a separate line, respectively, 9 and 10 for discharge and discharge of the working fluid with a pneumatic distribution device 11. A pneumatic distribution device 11 is connected through an air-controlled unit 12 to a high pressure line 13 and is connected to an electromechanical converter 15 connected to a master oscillator 14 torus.

The air motor operates as follows.

The compressed air is supplied to the working cavities 2 and 3 of the chamber 1 under pressure through the high pressure line 13 through an air-controlled unit 12 by means of a pneumatic distribution device 11. The air-controlled unit 12 carries out air preparation, purification and filtration, and regulation of the supply and pressure. With a positive signal U ₁₄ (FIG. 2) of the master oscillator 14, the electromechanical converter 15, by its control action U _15, connects the movable element of the pneumatic distribution device 11 to the discharge and discharge lines 9, the cavity 2 of the chamber 1 is filled with compressed air under pressure P ₁ , the cavity 3 at this along the discharge and discharge lines 10 is connected to the atmosphere. Due to the pressure difference in the cavities 2 and 3, the piston 4 moves down and through the rod 5, the connecting rod 6 and the crank 7 sets in motion a crank mechanism 8, which creates a torque M _cr on its shaft. When the signal U _{14 of the} master oscillator 14 is zero, the electromechanical converter 15, by its control action U _15, connects the movable element of the pneumatic switchgear 11 to the discharge and discharge lines 10, the cavity 3 of the chamber 1 is filled with compressed air under pressure Р ₂ , the cavity 2 is then fed along the discharge line and discharge 9 is connected to the atmosphere. Due to the pressure difference in the cavities 2 and 3, the piston 4 moves up and through the rod 5 drives the crank mechanism 8. During operation, the piston 4 and its rod 5 make reciprocal movements X and due to this the connecting rod 7 rotates the crank mechanism 8. The frequency of the control signals of the master oscillator 14 corresponds to a certain load on the shaft of the crank mechanism 8.

The operation of the air motor does not depend on environmental conditions; during its operation, available compressed air is used, which makes it possible to simplify the design of the air motor and increase its efficiency.
