Abstract
A junction element for a hydraulic fluid circuit, comprising a body (1) which is provided with inner channels (2,3) leading in an outer direction through a plurality of connection elements (7,8,9,10) which can cooperate with outer channels and with the support (12) of at least one sensor (13) for the value of a physical parameter of the fluid circulating in one of the inner channels (2,3) of the body.
Claims6
1/ A junction member for a hydraulic-fluid circuit, the junction member being characterized in that it comprises a body (1) provided with internal channels (2, 3) opening to the outside through a plurality of connection members (7, 8, 9, 10) capable of co-operating firstly with external pipes, and secondly with the support (12) of at least one sensor (13) for sensing a physical characteristic of the fluid flowing through one of the internal channels (2, 3) of the body.
2/ A junction member according to claim 1, characterized in that since the support (12) for the sensor (13) is in the form of a spigot having an end suitable for connection to an active sensor portion (13), the internal channels of the body include a chamber (17) having a wall that includes the connection means (8) for connecting the support of the sensor in a position such that the active portion (13) of said sensor is situated in the chamber (17).
3/ A junction member according to claim 2, characterized in that the body (1) includes a defining wall (18, 19) for defining the chamber (17), the wall being provided with at least two orifices (5, 6) each extended beyond the chamber (17) by connection means (9, 10) for connecting to an external pipe.
4/ A junction member according to claim 3, characterized in that the body (1) includes a third orifice (7) passing through connection means (11) for connecting to an external pipe, and in that the internal channels include a bypass channel (20) so as to avoid the active portion (13) of the sensor, and so as to connect the third orifice (7) to one (5, 6) of the other two orifices, said bypass channel being formed by a partitioning element for partitioning the chamber (17).
5/ A junction member according to any one of claims 2 to 4, characterized in that the connection (8) for connecting the body (1) to the sensor support (12) is a rotary connection.
6/ A junction member according to claim 5, characterized in that the axes of the connection means (9, 10, 11) of the body are in a plane containing the axis of the connection (8) for connecting the sensor support (12) to the body (1).
