Embodiment Construction

[0028] refer to Figure 1 to Figure 4 , the valve 100 according to the invention comprises a body 1 delimiting a seat 2 for a valve 3 associated with one end of a rod forming a slide 4 mounted in the body 1 in a blocking position In the blocked position, the valve 3 bears against the base 2 and in the open position, the valve 3 is moved away from the base 2 .

[0029] A motor 5 is fixed in the body 1 to drive the slide 4 and thus the valve 3 in translation. The motor 5 has an output pinion 6 which is connected via a gear set 7 to a pinion 8 formed by tooth segments. The gear set 7 is installed on the body 1 . The output pinion 6 , the gear set 7 and the pinion 8 pivot about an axis parallel to the sliding direction A of the slider 4 . The pinion 8 is associated with means generally indicated at 9 for converting the rotational movement of the pinion 8 into a translational movement of the slide 4 .

[0030] The device 9 comprises a support member 10 fixed in the body 1 in th...

Abstract

The subject of the invention is a device for converting a pivoting movement of a pinion (8) into a movement in translation of a slide (4), the device comprising: -a support member (10) for the slide and a support element (17) connected to the rotating pinion and connected to the slide moving in translation, the pinion being mounted in a pivoting manner with respect to the support member (10), which has a fixed tubular wall (11), the tubular wall being provided with at least one cam surface (15) that cooperates with a cam follower (16) mounted on the support element (17), the pinion being supported by the support member coaxially with the tubular wall, and -an element (25) that forms an angular stop and is arranged between the slide (4) and the support element (17) so as to allow the bidirectional rotation of the support element (17) with respect to the slide (4) through only a given angular portion.

Description

technical field [0001] The invention relates to a device for converting the pivotal movement of a pinion into a translational movement of a slide and a valve comprising such a device. A valve of this type can be used, for example, in the exhaust gas recirculation circuit of a heat engine of a motor vehicle. Background technique [0002] Such valves generally consist of a body in which is slidably mounted a valve connected to the output by means for converting the pivotal motion of a pinion meshing with the output pinion of a rotary motor into a translational motion of a slide The pinion, which is connected to the valve and is slidably mounted in the body through a guide sheath. The pinion is mounted to pivot relative to a support member of the slider, the support member comprising a tubular wall mounted fixed in the body. The tubular wall is provided with cam surfaces, each cooperating with a driven roller mounted on a support element driven in rotation on the one hand by ...
