Embodiment Construction
[0089] figure 1 Shown is an apparatus 400 for adjusting the compression ratio of a variable compression ratio engine comprising: means for closing at least one conduit connecting the upper chamber 121 and the lower chamber 122 of the hydraulic double-acting control actuator 8, and enabling The closing device is raised from its seat to allow hydraulic fluid to pass through the lifting device 410 in both directions.
[0090] According to various patent applications and patents belonging to the applicant, the variable compression ratio engine comprises a mechanical transmission 1 comprising, at the lower part of the combustion piston 2, a so-called "piston rack" fixed to said piston The transmission part 3 cooperates with the rolling guide 4 on the one hand and with the gear 5 on the other hand.
[0091] The transmission or piston rack 3 fixed to the combustion piston 2 is arranged such that at least one of its surfaces has a first large rack 35 whose toothing 34 cooperates with...

The device for adjusting the compression ratio of a variable compression ratio engine comprising a double-acting hydraulic control actuator (8) comprising an upper chamber (121) and a lower chamber (122) and at least one actuator piston (13) connected to a control rack (7) comprises: at least two balls (401, 402) or shutters each resting on a seat (403, 404) and each respectively closing off one end of a transfer port (405) connecting the upper chamber (121) and the lower chamber (122) of the control actuator (8), the said balls (401, 402) acting as non-return valves when held on their seat (403, 404) by a spring (408, 409) so as to allow hydraulic fluid to pass only in one direction; and lift means (410) allowing the balls (401, 402) to be lifted off their seat (403, 404) so that the said balls allow hydraulic fluid to pass in both directions.
Description
technical field [0001] The subject of the invention is a ball-lift device for adjusting the compression ratio of a variable compression ratio engine, comprising at least one ball or valve element arranged on a seat to close at least one upper chamber connected to a control actuator and The tubing of the lower chamber, when said ball or valve element is held in place by a spring, acts as a non-return valve element, so as to allow hydraulic fluid to pass in one direction only, and can be raised from the seat by means of a lifting device, so as to allow Hydraulic fluid passes in both directions. Background technique [0002] The Applicant's International Patent Applications WO98 / 51911, WO00 / 31377, WO03 / 008783 disclose various mechanisms for variable displacement engines. [0003] It is noted that the Applicant's International Patent Application WO98 / 51911 discloses a device for increasing the capacity of motors used at variable loads and speeds by adjusting their effective dis...
