Abstract

A device for producing compressed air stably and efficiently. A plurality of cams are set on one cam shaft and a pair of confronting separation plunger pumps are mounted via a tension spring to hold respective cams therebetween. Compressed air is produced by rotating the cam shaft and driving the pair of separation plunger pumps with the respective cams.

Description

Multiple antipodal symmetry type cam driven plunger pump Technical Field

The present invention relates to a gas intake / exhaust structure, which is a counter-symmetrical-type plunger pump, in which a flywheel is attached to a power source camshaft and rotation is increased as a positive cam, and the piston pump reciprocates at high speed. Background art

Conventionally, positive displacement compressors use a reciprocating piston movement, a crank rotation structure with large torque fluctuations, low speed rotation, high noise and vibration, and an efficient system

Problems to be solved by the invention

In order to solve the above problems, a pair of opposing plunger pumps are arranged on a straight line, and the reciprocating stroke is driven at a high speed to increase the intake and exhaust of the pump. Means for solving the problem

In order to solve the above-mentioned problems, the present invention reduces the displacement of the rotating cam in the reciprocating biston in a pair of plunger pump cylinders facing each other, makes the reciprocating stroke smaller than the biston diameter, and increases the speed. Increase gas discharge pressure and discharge volume with multiple combinations of jar pumps. The invention's effect

BEST MODE FOR CARRYING OUT THE INVENTION FIG. 1 is a schematic cross-sectional view of an anti-symmetrical cam-driven plunger pump. Gas intake A and compressed exhaust E are performed by repetitive movements of the plunger pump reciprocating motion S. The cam 2 and flywheel 2 ′ set on the camshaft rotate smoothly, and the intake and exhaust are alternately returned by the piston rod 4 and piston 5 in the cylinder 6 through the cam follower 3. The structure of the plunger pump is one pair, so the work for two cylinders of a conventional air compressor is carried out with 2 rotations, and 5 operates twice. Reducing the displacement D. of 2 from the diameter of 5 and shortening S of 5 and reciprocating the guide bolt 10 fixed to the mount base 9 in order to ensure that 3 follows the contour of 2. Fix 4 to guide base 1 2 with motion bearing 1 1 installed, and attach tension spring 1 3 to 1 2 and use S as a positive cam to ensure high-speed drive. Switching between A and E is performed with S of 5 in the exhaust chamber 14 in the intake chamber 14 in the cylinder head 7 and exhaust 1 7 'in the exhaust chamber 17. FIG. 2 is a sectional view of the cylinder head 7.

Intake chamber 1 1 4 · Intake ball 14 '(light specific gravity material) and exhaust chamber-1 7 · Exhaust pole 1 Ί' (light specific gravity material) are synchronized with A · E respectively. Acts as a pole valve. In each process, in order to prevent 1 4 '. 1 7' from falling off when opened, an intake wire gauge net 1 5 and a pneumatic wire gauge net 1 8 are provided. FIG.

Since S of 5 is operating at high speed, the temperature of E gas rises during the compression process, so a cooling fin is installed at the bottom of 5 and the cavity of cylinder bottom 8 'mount base 9 is forced to flow with S of 5 Reduces temperature rise of 4 · 5 · 6 by using outside air.

Industrial applicability

Due to the need for energy-saving air compressors, for the purpose of reducing power consumption,
