Embodiment Construction

[0068] figure 1 A cylinder block 100 is shown, which includes at least one cylinder 110, wherein the piston 2 is moved by the transmission device 1, and the pressure device can keep the main moving part of the variable volume ratio engine in its cylinder block in place.

[0069] At the lower part of the piston 2, the mechanical transmission device 1 includes a transmission member 3 fixed to the piston. The transmission member cooperates with the rolling guide device 4 on the one hand, and cooperates with the gear 5 on the other hand.

[0070] The gear 5 cooperates with the connecting rod 6 connected to the crankshaft 9 in order to transmit movement between the piston 2 and the crankshaft.

[0071] On the opposite side of the transmission member 3, the gear 5 cooperates with another rack, called the control rack 7. The vertical position of the control rack relative to the cylinder block 100 is controlled by the control device 12, which includes a control jack ( control jack) 8, guide ...

Abstract

The invention relates to a pressure device which maintains the raceways (48, 160 to 165) of the main moving components (3, 5, 7 and 40) of a variable compression ratio engine permanently in contact with one another and with the faces on which they rest in a cylinder case. The inventive device includes pressure means which are solidly connected to the cylinder case (100) and which exert a pressureforce on a control rack (7) having a toothed segment (75) formed by teeth (74). The pressure force is applied against a support surface (78) provided on the lower part of the rack (7).

Description

Technical field [0001] The present invention relates to a pressure device that keeps the raceways of the main moving parts of a variable volume ratio engine in constant contact with each other and in constant contact with the surfaces in the cylinder block supporting them. Background technique [0002] International patents WO98 / 51911, WO00 / 31377, and WO03 / 008783 belonging to the applicant disclose various mechanical devices of a variable volume ratio engine. [0003] It can be seen that the applicant’s international patent WO98 / 51911 describes a device for improving the use of variable load and speed internal combustion pistons by matching their effective displacement and / or their volume ratio during operation. The overall efficiency of the type engine. [0004] From the applicant’s international patents WO00 / 31377 and WO03 / 008783, it can be found that the mechanical transmission device of the variable volume ratio engine includes at least one cylinder in which a piston moves. The ...
