Power machine

Description

[0001] Power machine. The invention relates to a machine with a reciprocating piston, e.g. an explosion engine or a Steam engine, with two cylinders, each containing a pair of counter-rotating pistons. Each piston of a cylinder is connected to a piston of the other cylinder. The other cylinder is cross-coupled and works with it on the common crankshaft.

[0002] According to the invention, the opposing pistons of the two cylinders are connected by diagonal connections which are attached to the - The pistons at the same end of the cylinders are coupled by a rocker arm. The crankshaft is driven by a connecting rod from one of the The pistons are driven by diagonal connections. The connecting rod engages approximately in the middle of the connection.

[0003] Some embodiments of the invention are shown in the drawing.

[0004] Fig. z is a section through a cylinder of the machine omitting some parts, Fig. 2 is a plan view, Fig. 3 is a section in the right Angle to Fig. r.

[0005] Figures q, g and 6 show other embodiments.

[0006] All illustrations are purely schematic and show only those parts of the machine whose A diagram is necessary for understanding the invention. A, 4 are the cylinders, B is the base, C, Cl are the pistons. The machine has Four pistons, one pair in each cylinder A. The diagonal D connects the upper piston C in one cylinder to the lower piston Cl in the other. The cylinder is connected and is duplicated for force balancing and symmetry. E is a second diagonal, which is also duplicated. is the diagonal D crosses on the outside, as shown in Fig. 3, and connects the lower piston Cl of one cylinder with the upper piston C of the other. The crankshaft F is driven from the diagonal D by the connecting rod G. A rocker arm H connects the pistons C, which are located on the same The end of the cylinder lies there.

[0007] In the embodiment according to Figs. i to 3, the diagonals D and E sta rr are attached to heads c, cl of the pistons C, Cl. The diagonals D lies between the diagonals E and receives the crosshead bolt d, which connects the two diagonals D in the middle. It engages with them. the upper connecting rod head. The heads c of the upper pistons C carry bolts C2, which are connected by short links h with bolts hl at the ends of the The rocker arm H is connected. This rocker arm pivots around a pin h2, which is fixed in a cross piece b of the machine frame B. Diagonals D and E move in straight lines because they are directly connected to the ends of the pistons. However, one can use the The crosshead pressure connects to the bolt d, a crosshead dl which slides in a guide of the 2v machine frame. The guide consists of beer. Two pairs of rods b1 of rectangular cross-section, which pass through the machine frame from top to bottom. During the downward stroke, the Pistons are guided in the extensions .41 of the cylinders, which are provided with slots approximately for the passage of the heads cl, c and de- associated bolts. However, most of the crosshead pressure is absorbed by the sliding surfaces b1.

[0008] Instead of by means of the linkages l, the pistons can also be connected to the rocker arm H by means of slotted guides, as shown in Fig. .f. Here The bolts k3 of the lever H are connected to sliding pieces 1aI, which slide in slotted ends of the piston heads c-1. The heads c2 run on sliding tracks b2. at the top of frame B.

[0009] In the embodiment according to Fig. 5, the swing lift H is located at the bottom of the machine, directly above the crankshaft F and is connected to the lower piston C, C coupled. Otherwise, the arrangement is the same as shown in Fig. i to 3.

[0010] According to Fig. 6, the end of the diagonal D' lying on the side of the rocker arm H is not directly connected to the piston head c, but to connected to the bolt hl of the lever H. It must therefore describe a circular arc, which is why its connection to the piston C is via the linkage. la. To enable the slight circular movement of the diagonal Dl, it is made of two parts hinged together at the crosshead bolt d. Assembled. The crosshead dl receives the crosshead pressures.

[0011] According to the invention, a very compact and well-balanced power machine is obtained. The lateral forces are reduced to a minimum value. reduced, since the heavy drive and connecting elements run in as close to straight paths as possible. The lateral forces caused by The connecting rod drive is absorbed by the machine frame at points where a rigid mounting is readily possible.
