Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The invention relates to a unit consisting of a reciprocating piston machine and a transmission.

PRIOR ART According to DE 736 050, a reciprocating piston internal combustion engine is known which has two cylinders coaxially connected to one another in one unit.

In this known internal combustion engine, the cylinder is rotatably mounted in the mechanical housing as a unit. The pistons, which are movable rotationally in the two cylinders in the linear direction, are forcefully guided in opposite directions by means of a transmission arranged between the pistons. Projecting from these pistons are piston ronds, which at their ends opposite the pistons are provided with rollers each guided in an axial slit formed in the cylinder unit, as well as with a coiled self-containing roller. There are two bearings guided by cam tracks which are closed and fixed to the casing. Via the two pairs of rows of each piston, a type of connection is obtained in which the piston rotates with the cylinder and is also axially movable relative to the cylinder, as well as a reciprocating movement of the piston within the axially fixed cylinder. is obtained. The internal combustion engine is driven via gears arranged on a rotating cylinder unit.

In known transmission/internal combustion engine units, the axial structural length is equal to six times the length of the piston stroke. The transmission cannot be accessed without disassembling the piston/cylinder arrangement.

Known internal combustion engines are controlled by a slit placed in the outer periphery of a rotating cylinder. In a rotating cylinder,
Since a power outlet is provided, the sealing effect is problematic.

A hydraulic adjusting gear is known from U.S. Pat. No. 3,264,949.

In this known adjusting transmission, a piston of the pressurized cylinder unit, which can be driven translationally in two directions, drives the shaft in rotation via a ramp transmission, so that the rotational position of the shaft is corresponds to the stroke position of the piston. For this purpose, two pins are integrally formed in the piston, and these two pins engage two ramps rotating in opposite directions. One of these two ramps is fixedly connected to the shaft, whereas the other ramp is fixedly connected to the pressure cylinder unit. However, the adjusting gear only carries out a pivoting movement through an angle of less than 180°.

SUMMARY OF THE INVENTION It is an object of the present invention to improve the known unit consisting of a reciprocating piston machine controlled by a rotating slider and a transmission so that the reciprocating piston machine retains the advantages of the transmission structure. The object of the present invention is to provide a cylinder in which the axial space required for the cylinder is reduced.

Means for Solving the Problem The invention solves this problem in that the piston-cylinder arrangement has a cylinder member fixedly connected to the casing of the transmission, the cylinders being connected by a common piston to two cylinders. A working space is defined in which the piston is connected to a second transmission part of the transmission device via a piston rod guided through the end wall of the cylinder in a sealed manner.

Reciprocating piston machines are piston pumps or piston internal combustion engines. To control the valves of the reciprocating piston machine, preferably the rotational movement of the second gear part or the piston rod is used. The rotary slides of the mouth valve and outlet valve rotate outside of the stationary cylinder. The transmission is flange-connected to the side of the piston-cylinder arrangement and can be easily removed. The work cycles in the two work rooms are staggered in time with respect to each other, which increases work efficiency. If this reciprocating piston machine is used in particular as a piston pump, a high pumping efficiency can be achieved with small construction dimensions or a reduction in the pulsation of the pumped liquid can be achieved if the two working chambers are connected to each other on the outlet side. It will be done. A unit consisting of a reciprocating piston machine and a transmission according to the invention! Although it is used in four-stroke internal combustion engines, it can also be used in two-stroke internal combustion engines.

Embodiment According to an advantageous embodiment of the invention, the first transmission part is designed as a gear wheel rotatably but axially immovably journaled in the housing, and the second transmission part is , which is configured as a rod with a polygonal cross-section extending in the direction of movement of this second gear part, which rod is inserted into an opening of the gear wheel adapted to the polygonal cross-section of the rod. It is movably penetrated. The rod is journaled in a sliding bearing of the gear, but advantageously a linear rolling bearing is arranged in the opening of the gear, which guides the rod non-rotatably but axially movably. The rolling elements are arranged eccentrically with respect to the symmetrical plane of the polygonal surface so that torque can be transmitted well. The rolling elements used are balls or cylinders whose shafts are guided freely in a cage, for example a cage for an endless row of rolling bodies. However, it is also possible for the rolling elements to be individually mounted or guided on the shaft of the rolling bearing.According to a further embodiment of the invention, the cam track is located in the second transmission part. at least one sliding surface section extending around the rotational axis of the second gear part and rising in the direction of movement of this second gear part; and at least one sliding surface section extending around the same rotational axis and lowering in the direction of movement , and these rising and descending sliding surface sections are provided in pairs and extend alternately in the circumferential direction.Depending on the number of pairs of rising and descending sliding surface sections, The number of stroke movements of the cam follower per revolution of the rotating transmission part is defined and is preferably small (both pairs of rising and falling sliding surface sections are provided. The sliding surface section and the descending sliding surface section preferably extend in mutually opposite directions, so that the reciprocating movement of the cam follower is guided in a frictionally connected manner by the sliding surface section. For example, it has a waveform shape in consideration of the acceleration ratio of the cam follower.

The transmission according to the invention is suitable for converting a rotary movement of a drive machine into a linear movement of a piston of a piston pump or for converting a linear movement of a piston of a reciprocating piston internal combustion machine into a rotational movement of a drive shaft. The piston of such a machine preferably extends in the direction of the axis of rotation of the rotatable transmission part, in particular coaxially with this axis of rotation.

Piston pumps or piston internal combustion engines of this type have an outlet valve and an outlet valve. The second transmission part not only carries out a shearing movement, but also a rotary movement together with the first transmission part.

This rotational movement is used to control a rotary slider valve, the rotary slider of which rotates together with the second gearing part and is movable in the axial direction with respect to this second gearing part. connected. For this purpose, the rotary slide is arranged essentially coaxially with respect to the axis of rotation of the second transmission part. Thus, for example, the rotary slide can be arranged on the end side of a cylinder of a pump or internal combustion engine, which is also arranged co-dynamically with respect to the second transmission part, and which is connected to the inlet and outlet valves of the two working chambers. and are advantageously controlled so that they are alternately opened and closed. This embodiment is particularly advantageous for piston pumps. This is because the reciprocating stroke of the piston is used as the reciprocating stroke of the pump. This piston pump has small construction dimensions and high pumping efficiency. Furthermore, if the two working chambers are connected to each other on the outlet side, the pulsations of the pumped liquid are reduced. The piston-cylinder arrangement described above is particularly suitable for four-stroke internal combustion engines, but can also be used for two-stroke internal combustion engines.

A two-stroke internal combustion engine using a transmission according to the invention is known from DE 30 29 287 A1.

This internal combustion engine is configured as a two-stroke internal combustion engine, and the two-stroke internal combustion engine has three cylinder chambers arranged on the same axis and sealed from each other, in each of which a piston rod is inserted. Each one of the six pistons is movably arranged, fixedly connected to each other in the direction of movement via a cylinder, the medium-heat cylinder chamber being divided into two chambers by the central piston. The six pistons are arranged to control each valve slit in its cylinder chamber and an overflow passage between adjacent cylinder chambers, possibly communicating with the piston rod. In this internal combustion engine, the two outer cylinder chambers form a combustion chamber, whereas the central cylinder chamber is divided by a central piston into two charging chambers. With this arrangement, difficulties arise in the power take-off since it is formed on the "hot" side of the combustion chamber.

In order to avoid such disadvantages, in particular of heat transfer, it is advantageous if the central piston divides the central cylinder chamber into two combustion chambers, and the two combustion chambers have one or more common pistons. The two outer cylinder chambers are designed to control separate valve slits for the discharge, and the two outer cylinder chambers are designed for the intake.This type of internal combustion engine has a separate transmission system, which is different from the transmission described above. The internal combustion engine can also be connected directly to a piston pump with a reciprocating movement of six pistons or to the pistons of another working machine.In this case, the internal combustion engine is preferably connected to the working machine. is immovably connected to.

Embodiments and Operations Next, the structure and operations of the present invention will be specifically explained with reference to the embodiments shown in the drawings.

FIG. 1 shows a reciprocating piston machine according to an embodiment of the invention.
A transmission 1 of a transmission unit is shown schematically. An input shaft γ is rotatably supported within a casing 5 of this transmission device 1 . This input shaft 7 has a pinion 9
is mounted so that it cannot rotate. This pinion 9 meshes with a gear 11 (first transmission part), and this gear 11 is rotatably supported within the casing 5 via ball bearings 13 provided on both sides so as to be rotatable about a rotation axis 15. has been done. Triangular cross-sectional shape and flat polygonal surface 19
an elongated rod 17 (second transmission part) with
passes through an opening 21 provided in the center of gear 11, as shown in FIG. A rolling element 23 on a linear roller bearing guides the rod 17 so that it rotates together with the gear 11, but is movable in the axial direction relative to the gear 11. The rolling elements 23 are arranged eccentrically with respect to the longitudinal symmetrical plane of each polygonal surface 19 in order to reliably transmit torque. This linear rolling bearing is a ball box type rolling bearing with an endless row of rolling elements. However, the rolling element 23
may be constructed as a bearing roller or the like. The rod 17 is non-rotatably connected to a cam follower 25 of a cam transmission 27. The cam follower 25 follows in a frictional manner a cam track 31 formed in the shape of a groove in the inner circumferential wall of the hollow cylindrical casing part 29 . The cam track 31 may coaxially surround the rotation axis 15 of the gear 11 and thus the rod 17 and the cam follower 25.

3, a developed view of the inner circumferential wall of the casing part 29 (as can be seen, the cam track 31 has a pair of circumferentially continuous ascending sliding surface sections 33 and descending sliding surface sections 35). The number of sliding surface sections in this pair determines the number of reciprocating movements of the cam follower 25 and thus of the rod 17 per revolution of the gear 11. The sliding surface sections 33 are ascending and the sliding surface sections 33 are descending. Slip surface classification 3
5 and 5 face each other in the direction of the rotational axis 15, the reciprocating motion of the cam follower 25 is obtained in a frictional manner.The cam track 31 has a waveform shape, for example.In the illustrated embodiment, two Pairs of sliding surface sections are provided; other numbers of pairs of sliding surface sections are also possible.

Similarly, the cam follower 25 has two follower arms 37 diametrically opposed to each other, as shown in FIG. At its radially outer end, this follower arm 37 has a roller 39 which is rotatable about a radial axis of rotation and which engages the cam track 31 .

Even if only one follower arm is sufficient,
In order to obtain good force transmission, it is advantageous to provide as many follower arms as pairs of sliding surface sections. In FIG. 5, a piston pump 101 is shown. This piston pump 101 is driven via a transmission 1 according to FIG. The piston pump 101 has a cylinder 103, which is partitioned into two working chambers 107 and 109 by a piston 105. These work rooms 1
07 and 109 are also controlled to mutually perform suction or discharge operations.

A piston rod 111 rotatably supported by a cylinder 103 and a piston 105 is connected to the rod 11 of the transmission 1.
is immovably connected to. The working chamber 101 is controlled by a rotary slider 113. This rotary slider 113 is rotatable but immovable in the axial direction, and is
It is arranged coaxially with respect to the piston rod 111 in front of the end wall of the cylinder 103, which limits the piston rod 111. The piston rod 111 has a footrest slide key 115 which is movably arranged in an axial groove 117 of the rotary slider and which prevents the piston rod 111 from rotating relative to the rotary slider. , but is axially movably connected to the rotary slider 113. The rotary slider 113 has a suction slit 119, which is connected to the working chamber 107.
The connection between the suction opening 121 and the suction passage 123 is controlled.

The suction slit 119 and the suction opening 121 form a suction valve. The rotary slider 113 has a discharge slit 125 that is angularly shifted from the suction slit 119 in the radial direction. This discharge slit 125 connects the discharge opening 127 of the working chamber 107 to the discharge passage FMr129. The discharge slit 125 and the discharge opening 127 form a discharge valve.

The piston rod 111 passes through the piston 105 and into a further working chamber 109 into the cylinder 103 on the side opposite to the drive side. On the opposite side of the cylinder 103 from the drive side, another rotary slider 131 is arranged mirror-symmetrically. This further rotary slider 131 is connected to the rotary slider 131 immovably, but axially movably, via a slide key 133 fixed to the piston rod and guided in an axial groove 135 of this rotary slider 131. has been done. The rotary slider 131 has a discharge slit 137 for controlling the connection between the detailed opening 139 of the work chamber 109 and the discharge passage 141, and a suction slit 143 for controlling the connection between the suction opening 145 and the suction passage 147. have. The discharge slit 137 and the discharge opening 139 form a discharge valve, and the suction slit 143 and the suction opening 145 form a suction valve. Rotating slider 11
The slits 3 and 131 are arranged so that the compression stage and the suction stage alternate in each of the two working chambers 107, 109, that is, one of the two working chambers works in the suction stage and the other works in the compression stage. They are arranged relative to each other so as to work in stages. Rotating slider 113, 131
is provided in front of the end face side of the cylinder 103 so as to be rotatable but immovable in the axial direction. in this case,
The number of suction slits 119 corresponds to the number of sliding surface segment pairs.
or 143 and discharge slit 125 or 137
(See Figure 4). Suction slit 11
9 or 143 and discharge slit 125 or 13
7 are offset relative to each other in the circumferential and radial directions, such that the suction openings 121 or 145 and the discharge openings 127 or 139 are alternately open or closed. Although the piston 105 is fixedly provided on the piston rod 111, it may be rotatably supported by the piston rod 111.

The mode of operation of this reciprocating piston mechanical and transmission unit is as follows.

When the input shaft 7 is rotated, the rod 17 is driven to rotate in a uniform direction about the rotation axis 15 via the pinion 9 and the gear 11. Piston 105 fixed to piston rod 111 so as not to be axially movable
is controlled by a cam transmission 27 to effect a reciprocating piston movement. That is, depending on the number of sliding surface segment pairs, two complete stroke movements are performed for every revolution of the gear 1101. A rotary slide 113, which is non-rotatably connected to the piston rod 111, opens the suction opening 121 and closes the discharge opening 127 at the beginning of the suction phase of the working chamber 107 (see FIGS. 4 and 5). Another rotational position of the cam gear 27, i.e. in the two pairs of sliding surface sections, is also the gear 11.
After the rotation of the rotary slider 113, the suction opening 1
21 is closed and the discharge opening 127 is opened.

The basic structure of the piston pump shown in Figure 5 is an internal combustion engine,
It can be used in particular in four-stroke internal combustion engines. For this reason, the spark plugs 151 and 153 for Otsudo engines are 81
indicated by a line.

These spark plugs 151, 153 are connected to the suction passage 12.
3. Alternately ignite the air/fuel mixture supplied via the 141'r, for example from a carburetor. In Figure 5, combustion chamber 1
07, the suction phase is shown with the suction opening 121 open. The suction slit 119 and the discharge slit 125 of the rotary slide 113 are arranged in such a way that the combustion chamber is closed during the subsequent compression phase and the subsequent working phase. The working phase is followed by an evacuation phase in which the discharge opening 127 is opened.

The work stages of work room 109, which performs the same continuous work as work room 107, are shifted with respect to the work stages of work room 1010. In the position shown in FIG. 5, the working chamber 109 is in the evacuation stage with the discharge opening 139 open. This evacuation phase is followed by a suction phase, a compression phase and then a working phase. Instead of the evacuation stage of the working chamber 109 shown in FIG. 5, the compression stage of the working chamber 109 can also be assigned to the suction stage of the working chamber 107 by correspondingly arranging the rotary slide 131.

In Figure 6, a longitudinal cross-sectional view of a two-stroke internal combustion engine 201 is shown. The piston stroke movement of this two-stroke internal combustion engine 201 is advantageously converted into a rotary movement of the working shaft via a transmission of the type shown in FIG. However, it is also possible to convert the piston stroke movement of the internal combustion engine 201 into a rotary movement or to transmit this piston stroke movement directly to the drive of a working machine, in particular a piston pump, by means of a transmission of other constructions.

The two-stroke internal combustion engine 201 has six cylinder chambers 203, 205, 207 arranged coaxially with each other. In each of these cylinder chambers 203, 205, 207 one piston 209, 211 or 213 can be moved in a sealed manner. The cylinder chamber is located in the transmission device 1 (
(see FIG. 1).

The pistons 209, 211, 213 are connected to a common piston rod 215, which is connected either non-rotatably or rotatably to the rod 17 of the transmission 1. center piston 2
11 is a central cylinder chamber with two combustion chambers 217 and 219.
one or more exhaust openings 221 (valve slits) arranged in the axially central position. The two outer cylinder chambers 203, 207 cooperate with the pistons 209, 213 arranged in the cylinder chambers and the cylinder chamber/partition wall 223 or 225 sealed against the piston rod 215 to form a precompression chamber, respectively. 227 or 229 is formed. The two outer pistons 209, 213 control the suction cylinders 231, 233 guided in the cylinder chambers 203, 207. Furthermore, the piston rod 215 has a central piston 72.

17 or 219. Spark plugs 239, 241 are arranged in the combustion chambers 217, 219 to ignite the air/fuel mixture.

Combustion chambers 217, 219 are alternately fed and evacuated and alternately ignited. FIG. 6 shows the combustion chambers 2 and 11 during ignition. At the time of this ignition, the suction slit 231 is open at f", so fresh air or air-fuel mixture is supplied to the compression chamber 221. The piston is pushed to the right by the working cycle (see Figure 6). , the suction slit 231 is closed and the supplied fresh air or air-fuel mixture is compressed.The pre-compression pressure is
The overflow passage 235 rises until it enters the cylinder chamber partition wall 223 and opens the precompression chamber 227 to the combustion chamber 211 . This condition is illustrated by overflow passage 237 in FIG. The fresh air or mixture thus precompressed flows from the precompression chamber 229 into the combustion chamber 219 via the overflow passage 237, whereas the exhaust gas is discharged via the exhaust slit 221. The central piston 211 moves in the reverse direction to close the exhaust slit 221 and performs a scavenging stroke until the fresh air or air-fuel mixture is newly compressed in the combustion chamber. Combustion chambers 217, 219 are fired alternately. moreover,
While fresh air or mixture is compressed in one combustion chamber,
The fresh air or mixture for the other combustion chamber is precompressed in the associated precompression chamber. Since the precompression chamber is located outside the combustion chamber, the working temperature inside the combustion chamber is high in order to burn fuel that is difficult to ignite. Nevertheless, a relatively cool fresh air or mixture is supplied.The power delivery member, here the piston rod 215, is guided from the casing of the internal combustion engine 201 to the relatively "cold" outside.The internal combustion engine is of the Otsudo type. Works on principle or diesel principle.

The pre-compression pressure and the compression pressure are applied to the outer piston 209.213.

The mixture may also be precompressed.

Advantages As described above, according to the invention, a unit consisting of a reciprocating piston machine and a transmission device has been obtained, in which the space required in the axial direction of the cylinder of the reciprocating piston machine is reduced.
