A length-adjustable connecting rod is disclosed having a longitudinal axis comprising a connecting-rod shank provided with at least one internal thread, at least one connecting element comprising an external thread cooperating with the internal thread of the connecting-rod shank, the screwing or unscrewing of the connecting-rod shank with respect to the connecting element allowing the length of the connecting rod to be adjusted, and at least one resisting torque device between the connecting-rod shank and the connecting element, the resisting torque device comprising at least one pressing element and a bearing element, the pressing element exerting a force on the bearing element that opposes a resistance to the rotational movement of the connecting-rod shank with respect to said connecting element. The bearing element is integral with the connecting element and the pressing element is integral with the connecting-rod shank.

An actuator of a variable compression ratio mechanism includes: a control link; an arm link; a control shaft; a housing including a receiving portion in which a connection portion between the second end portion of the control link and the arm link is received, and a support hole formed within the housing, and rotatably supporting the control shaft; and a speed reduction device, the control shaft including a fixing portion inserted and fixed within the receiving portion in a fixing hole formed in the arm link at a predetermined axial position, and a first journal portion which is formed at a tip end portion of the control shaft, which has a diameter smaller than a diameter of the fixing portion, and which is supported by a first bearing hole formed in the support hole.

The invention relates to a length-adjustable con rod (1) for a reciprocating piston engine, particularly an internal combustion engine, having at least a first and a second rod part (2, 4), wherein the two rod parts (2, 4) can be pushed together and/or inside one another in a telescoping manner, wherein the second rod part (4) forms a guide cylinder (4a) and the first rod part (2) a piston element (3) which can be pushed longitudinally in the guide cylinder (4a), wherein a high-pressure chamber (4b), into which at least one oil channel (10) opens, is clamped between the first and the second rod parts (2, 4). To enable the compression ratio to be adjusted in the simplest and most reliable manner possible, according to the invention the two rod parts (2, 4) can be fixed, by a locking device (32), relative to one another in at least one position, preferably corresponding to a minimum length of the con rod (1).

A terminal (10) for a motion transmitting remote control assembly (12) securable to a control member (14) in a vehicle includes a housing (44) for connection to a core element (20) of the motion transmitting remote control assembly (12) with the housing (44) defining an aperture (48) forming at least one open end (50). The terminal (10) also includes a connecting member (60) having a body (62) disposed in the aperture (48) with the body (62) having a cavity (66) for receiving the control member (14) and a groove (84) in communication with the cavity (66). The terminal (10) further includes a retainer (90) mounted to the connecting member (60) and disposed in the groove (84) of the body (62) with the retainer (90) disposed in the aperture (48) when the connecting member (60) is in the housing (44) and the retainer (90) extending into the cavity (66) for engaging the control member (14) to retain the terminal (10) to the control member (14) and to prevent non-destructive removal of the terminal (10) from the control member (14).

A connecting rod (10) has a big end bearing eye (11) for connection to a crankshaft, a small end bearing eye (12) for connection to a piston of a cylinder, and an eccentric adjustment device (13) for adjusting an effective connecting rod length. The eccentric adjustment device (13) has an eccentric (36) that interacts with an eccentric lever (14), and eccentric rods (15, 16) that the eccentric lever (14). The eccentric lever (14) has segments (38, 39) positioned axially in front of and behind the small end bearing eye (12). Each eccentric lever segment (38, 39) is connected to the eccentric (36) for conjoint rotation. Each eccentric lever segment (38, 39), end faces (43, 44) of the small end bearing eye (10) adjacent the respective eccentric lever segment (38, 39), and adjacent end faces (45, 46) of the eccentric (36) have a beveled contours.
