The left end of the left connecting rod is provided with a left piston, and the right end of the right connecting rod is provided with a right piston; the outer surface of the body is provided with a P oil port, T1 oil port, T2 oil port; the piston body is provided with a control assembly for controlling the piston body to move left and right in the installation hole; the outer circumference of the piston body is provided with a first communication groove, a second communication groove, and a third communication groove; The press is not only simple in structure and small in size, but also can control the automatic reciprocating movement of the piston body without electronic control.

Description

technical field [0001] The invention belongs to the technical field of air compressors, and in particular relates to a compact air compressor. Background technique [0002] With the large-scale application of large-scale mechanical equipment, the use of hydraulic drive technology in the field of air compressor application technology is becoming more and more mature. The traditional air compressor uses a crank connecting rod mechanism to realize the reciprocating movement of the piston in the cylinder and then compress the air. The output pulse of the air compressor of this method is large, unstable, and it is easy to get stuck under severe working conditions. In addition, most of the reversing valves that realize the reciprocating motion of the piston in the current hydraulic air compressors use electromagnetic reversing valves and displacement sensors to match each other. Cooperate with the control of the reversing, the sensor is controlled by the proximity switch, the reve...

[0002] With the large-scale application of large-scale mechanical equipment, the use of hydraulic drive technology in the field of air compressor application technology is becoming more and more mature. The traditional air compressor uses a crank connecting rod mechanism to realize the reciprocating movement of the piston in the cylinder and then compress the air. The output pulse of the air compressor of this method is large, unstable, and it is easy to get stuck under severe working conditions. In addition, most of the reversing valves that realize the reciprocating motion of the piston in the current hydraulic air compressors use electromagnetic reversing valves and displacement sensors. Cooperate with the control of the reversing, the sensor is controlled by the proximity switch, the reversing is unstable and unreliable; the control circuit part of the reversing device is controlled by the circuit board, because the circuit board is a non-standard part, and it is difficult to manufacture and process, and repair after damage It is very difficult; if the existing reversing device is continuously energized for a long time, it is easy to damage small devices, which cannot meet the requirements of long-term energization, and also affects the production efficiency to a certain extent; at the same time, when the piston moves to the terminal Impact collision of the cylinder block, resulting in collision noise and collision damage
