The articulated lever system with a crosshead is connected to the crankshaft and has a guide in the lower part of the crankcase (ed. St. USSR №905499, Ρ 01В 9/00, 1978).
A disadvantage of the known piston machine is that the issues of reducing the harmful space, decreasing its volumetric capacity, reducing the hydraulic losses in the valves, as well as sufficient cooling of the piston of the machine are not solved.
A piston machine is known, which contains a crankcase with a cylinder fixed on it, in which a piston with a rod, a cover installed on the cylinder, suction and discharge valves, two parallel crankshafts located symmetrically relative to the cylinder axis and connected with each other with the possibility of rotation in opposite directions are located the yoke connected to the piston rod, two connecting rods, each of which is pivotally connected to the corresponding crankshaft at one end and the other end connected to the corresponding crankshaft Aversa a piston rod pivotally connected to the cross member.

A disadvantage of the known piston machine when it is used as a compressor is the presence of significant detrimental space and significant hydraulic losses during the suction and discharge of the working fluid due to the suction and discharge valves on the cylinder head that increase the minimum volume between the cover and the piston due to the volume of valves and reducing the flow areas of both suction and discharge valves occupying together one surface of the lid, which lowers the volumetric production clusive piston machine and filling the cylinder with. In addition, in the piston machine is not provided sufficient cooling of the piston.
DISCLOSURE OF INVENTION
The problem solved in the invention is the creation of a piston machine, in which the reduction of the volume of harmful space, the reduction of hydraulic losses during suction and discharge and the cooling of the machine is ensured.
The task of creating a piston machine is solved by the fact that a piston machine contains a crankcase with a cylinder fixed on it, in which is placed a piston with a rod, a lid mounted on the cylinder, suction and discharge valves, two parallel crankshafts, symmetrically located relative to the cylinder axis and interconnected with the possibility of rotation in opposite directions, the traverse connected to the piston rod, two connecting rods, each of which is pivotally connected at one end to the corresponding crankshaft and the other to the hinge but is connected to the corresponding end of the traverse, the piston rod is connected to the traverse pivotally.
Distinctive features of the proposed piston machine from the above closest analogue are the piston with an internal cavity, and the rod with a through longitudinal-axial channel connected to the internal cavity of the piston, the installation of the suction nozzle in the crankcase coaxially with the rod, which enters the suction nozzle with the possibility of translational movement, the connection of the crosshead with the rod above the entrance to the suction nozzle, the installation of suction valves on the front wall of the piston, and the discharge valves on the ryshke.
Making a piston with an internal cavity, a rod with a through longitudinal-axial channel connected to the internal cavity of the piston, installing a suction nozzle in the crankcase coaxially with the rod, which enters the suction nozzle with the possibility of reciprocating movement, connecting the yoke with the rod above the entrance to the suction nozzle, installation of suction valves on the front wall of the piston, installation of pressure valves on the cylinder head allows you to create a minimum amount of harmful space of the piston machine (minimal The remaining volume between the cover and the piston), which leads to an increase in the volumetric productivity of the piston machine while creating a minimum amount of harmful space and increasing the flow areas in the suction and discharge valves by installing suction valves on the front wall of the piston, and the discharge valves in a different place - cylinder head, leading to a decrease in hydraulic losses in a piston machine, and when the piston moves from the upper to the lower position, ensure the suction of the working fluid through through the longitudinal-axial channel of the rod from the suction nozzle, the flow of the working fluid into the internal cavity of the piston and through the suction valves into the cylinder and from the cylinder when the piston moves in the opposite direction through the discharge valves flow to the consumer, leading to the cooling of the piston by the suction of the working fluid and as a result piston machine. The connection of the yoke with the rod above the entrance to the suction nozzle ensures the movement of the rod with the piston. Installation of suction valves on the front wall of the piston, and
- 1 007478 pressure valves on the cylinder head reduces the volume of harmful space by moving the suction valves to another location and increase the margins of the suction and discharge valves again by placing less pressure valves on the same area and the same amount suction valves, which leads to a decrease in hydraulic losses and an increase in volumetric capacity and filling the cylinder with the working fluid.
It is possible to perform a through longitudinal axial channel of the rod with a diffuser on the side of connection with the internal cavity of the piston and with a confuser on the side of the entrance to the outlet nozzle, which makes it possible to reduce pressure losses during the movement of the working fluid along the longitudinal axial channel by ensuring the minimum flow rates of the working body during the entrance to the channel of the rod and the exit from the channel of the rod into the internal cavity of the piston and thereby increase the filling of the cylinder with the working fluid.
It is possible to install pressure valves on the cylinder head with the possibility of being flush with the surface of the cover on the piston side in the closed position, which allows reducing the volume of harmful space by creating a flat surface of the cover on the piston side.
It is possible to install suction valves on the front wall of the piston with the possibility of being flush with the surface of the front wall of the piston in the closed position, which allows reducing the volume of harmful space by creating a flat surface of the front wall of the piston.
Brief description of the invention
FIG. 1 shows a longitudinal section of a piston machine, made in the form of a piston compressor; in fig. 2 - top view of the traverse.
The best embodiment of the invention
A piston machine made in the form of a piston compressor contains a crankcase 1 with a cylinder 2 fixed on it, in which a piston 3 with a rod 4 is mounted, a cover 5 mounted on cylinder 2, two parallel crankshafts 6 and 7 with counterweights located symmetrically relative to the axis of the cylinder 2 and interconnected with the possibility of rotation in opposite directions using mated cylindrical gears 8 and 9.
The cross member 29 is connected to the stem 4, two connecting rods 10 and 11, each of which is pivotally connected at one end to the corresponding crankshaft 6 or 7, and the other end is pivotally connected to the corresponding end of the crosspiece 29 by means of two earrings 25 and 26 with fingers fixed to them 22 and 23. The rod 4 in the zone of connection with the rods has a local square cross section. The piston rod 4 of the piston 3 is connected to the crosshead 29 pivotally by the axis 21.
The piston 3 is made with an internal cavity 12. The rod 4 is made with a through longitudinal-axial channel 13 connected to the internal cavity 12 of the piston 3. The suction nozzle 14 is installed in the crankcase 1 coaxially with the rod 4, which enters the suction nozzle 14 through the seal 15 with the possibility of returning -accessive movement along the guides. The cross member 29 is connected to the rod above the entrance to the suction nozzle 14 while the piston 3 is in the lower position. The suction valves 16 are installed on the front wall 17 of the piston 3, and the discharge valves 18 are installed on the lid 5. The discharge valves 18 on the lid 5 are hydraulically connected to the receiver 19 which is in turn connected to the exhaust port 20.
Suction valves 16 can be installed on the front wall 17 of the piston 3 so that it can be flush with the surface of the front wall 17 of the piston 3 in the closed position.
The discharge valves 18 can be mounted on the cover 5 with the possibility of being flush with the surface of the cover 5 on the side of the piston 3 in the closed position.
Through the longitudinal-axial channel 13 of the rod 4 can be made with a diffuser 27 from the connection with the internal cavity 12 of the piston 3 and confuser 28 from the entrance to the suction nozzle 14.
Suction and discharge valves 16 and 18 can be made in the form of self-acting automatic valves.
The discharge valve 18 can be made controlled.
The suction valves 16 on the front wall 17 of the piston 3 can be made in the form of conical plates tightly seated in conical holes in the front wall 17 with pins and limiters on the end.
The discharge valves 18 on the lid 5 can be made with guides in the form of conical plates set in conical holes in the lid 5 with pins springed in the direction of the lid 5.
Similarly, a piston engine can be made in a variant of a four-stroke internal combustion engine with replacement of injection valves with controlled inlet valves and an additional fuel injection nozzle directly into the cylinder mounted on the cylinder head. The piston machine can also be designed as a pump.
Piston machine as a piston compressor operates as follows.
During the rotation of the crankshafts 6 and 7, the piston 3 reciprocates in the cylinder 2. When the piston 3 moves from the top position to the bottom, the suction valves 16 on
- 2 007478 the front wall 17 of the piston 3, when it is accelerated down, self-opens due to the action of inertia forces, remaining on the stops, and the working fluid is sucked through the suction nozzle 14 and through the longitudinal-axial channel 13 of the rod 4 into the internal cavity 12 of the piston 3 and through the holes in suction valves 16 per cylinder 2.
Upon further rotation of the crankshafts 6 and 7, the piston 3 stops and begins to move upwards, the suction valves 16 close by creating acceleration of the piston 3 upwards. After compressing the working fluid in the cylinder 2 to the pressure in the receiver 19, the discharge valves 18 self-open to overcome the force of pressing their springs, the working fluid enters the receiver and exits through the outlet 20 to the consumer, after which the cycle repeats.
When moving the working fluid through the longitudinal-axial channel 13 of the stem 4 with the diffuser 27 and the confuser 28, the pressure loss of the working fluid decreases by ensuring minimum flow rates of the working fluid when entering the longitudinal-axial channel 13 of the stem 4 and leaving it into the piston cavity, where pressure is restored.
When carrying out the process of forcing the working fluid in a piston compressor with discharge valves 18 installed on the lid 5 so that it can be flush with the surface of the lid 5 on the side of the piston 3 in the closed position, the amount of harmful space is reduced by creating a flat surface of the lid 5.
When carrying out the process of forcing the working fluid in a piston compressor with suction valves 16 mounted on the front wall of the piston 3 with the possibility of being flush with the surface of the front wall 17 of the piston 3 in the closed position, the volume of the harmful space is reduced by creating a flat surface of the front wall of the piston 3.
Industrial Applicability
The most successful of the present invention can be used in compressors, pumps or internal combustion engines.
