The invention relates to engine.

A device for elastic connection between the piston and crankshaft, containing a piston, a connecting rod, the upper cylinder, which has a convex cylindrical surface in contact with the surface of the piston and covered by the flexible element, the coils of which is placed on the cylindrical surface of the upper head, and the ends of the flexible element missing in contact with the upper head surface of the piston and secured in the piston (SU 1590770, F16J 1/14, publ. 1990). The known device has a complex structure.

Also known device for elastic connection between the piston and the crankshaft, containing a piston, the rod and the Assembly unit consisting of a flexible elements-torsions (DE 4040274, publ. 1992).

The known device has a complex structure Assembly unit.

The objective of the invention is to simplify the design of an Assembly unit.

The problem is solved in that the device for elastic connection between the piston and the crankshaft, containing a piston, the rod and the Assembly unit consisting of a flexible elements-torsions, Assembly unit contains three intermediate sleeve that hold the torsions.

The invention is illustrated in the drawing, in which figure 1 shows a General view of the device, figure 2 shows the device at the moment is asgarnia fuel.

The device comprises a piston 1, the rod 2 and the Assembly unit containing three intermediate sleeve 3, 4, 5, and flexible elements 6 torsions, and two sleeves 3 and 5 are installed in the piston, and one 4 - in top head of a rod.

When the ignition of fuel in the combustion chamber increases the pressure, causing the piston 1 with the sleeves 3 and 5 moves down, flexing torsions 6. When the pressure decreases as the movement of the piston 1 down together with the sleeves 3 and 5 torsions are straightened and the piston 1 with the sleeves 3 and 5 occupies its original position, thereby maintaining the pressure in the combustion chamber at a higher value, increasing the torque on the shaft of the internal combustion engine that allows you to accumulate and release energy during movement of the piston down.

For a device characterized by the following:

- small dimensions;

- the possibility of replacing the piston pin for the Assembly unit in already working engine during repair;

- does not change the design of the internal combustion engine.

Device for elastic connection between the piston and the crankshaft of the internal combustion engine, containing a piston, the rod and the Assembly unit consisting of a flexible elements-torsions, wherein the Assembly unit contains three intermediate sleeve that hold the torsion./p>

SUBSTANCE: device incorporates a screw, a nut, a clamp representing a tape with a hole for the pin to pass through, a rod, two props rigidly interconnected by a crosspiece with the hole and two couplers. The crosspiece support the nut with screw. One end of the clamp is attached to one of the crosspieces, its other end being linked to the tie-rod furnished with awing nut and passing through the support hole. The support represents the L-shape plate with its longer shoulder fitted in the gap between the clamp and stiffness rigs and its central part having a bend forming an additional shoulder resting upon the other clamp. To add to the stability, the base of one prop has the diameter matching that of the piston radius while that of the other prop matches the radius of piston ring groove. Here note that the screw is linked, via an expansion spring, to the rod free end supporting the guide sleeve and piston pin. The rod other end is furnished with the limb and handle. The limb can be represented by the handle lock nut.

EFFECT: possibility of using device in both stationary conditions and in situ.

Loading assembly // 2330195

FIELD: engines and pumps.

SUBSTANCE: loading assembly relates to machine building hydraulics and can be used to create loads in testing service units and adjusting hydraulic boosters. A variable dynamic load in the loading assembly is created by one spring working in compression and generating equal rod force in the "OUT" and "IN" travel from neutral. Availability of adjusting nut allows varying the rod backlash (rod travel from neutral with origination of a dynamic load). The use of elastic rings, adjusting stops, spaces filled with lubricating grease allows simulating load initiated by friction force.

EFFECT: higher reliability.
