Abstract
Abstract 1. Electromagnetic relay containing a magnetic circuit consisting of a yoke (16) with two vertical branches (20, 22) between bases (26, 28) whereof a permanent magnet is installed, and of a moving flap closing the magnetic circuit, together with a control circuit coiled on one (20) of the vertical branches (20, 22) of the yoke, characterized in that bases (28) of the said vertical branches (20, 22) are connected together by a horizontal magnetic shunt branch (34) parallel to the lines of force of the magnetic flux created by the permanent magnet.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
95 words
Electromagnetic relay (10) containing a magnetic circuit consisting of a yoke (16) with two vertical branches (20, 22) between bases (26, 28) whereof a permanent magnet (24) is installed, and of a moving flap (18) closing the magnetic circuit, together with a control circuit (40) coiled on one (20) of the vertical branches (20, 22) of the yoke, characterized in that bases (28) of the said vertical branches (20, 22) are connected together by a horizontal magnetic shunt branch (34) parallel to the lines of force of the magnetic flux created by the permanent magnet.
Claim 2
Dependent Claim
95 words
Electromagnetic relay (10) containing a magnetic circuit consisting of a yoke (16) with two vertical branches (20, 22) between bases (26, 28) whereof a permanent magnet (24) is installed, and of a moving flap (18) closing the magnetic circuit, together with a control circuit (40) coiled on one (20) of the vertical branches (20, 22) of the yoke, characterized in that bases (28) of the said vertical branches (20, 22) are connected together by a horizontal magnetic shunt branch (34) parallel to the lines of force of the magnetic flux created by the permanent magnet.
Claim 3
Dependent Claim
29 words
Relay as claimed in claim 1, characterized in that the said vertical branches (20, 22) and the said horizontal branch (34) form a single part (16) in magnetic material.
Claim 4
Dependent Claim
38 words
Relay as claimed in claim 2, characterized in that the said single part (16) is obtained by cutting out a plate in magnetic material and bending it parallel to the vertical direction of the said branches (20, 22).
Claim 5
Dependent Claim
39 words
Relay according to any one of claims 1 to 3, characterized in that the said permanent magnet (24) is a rectangular parallelepipedic magnet whose two polar faces (30, 32) are parallel to the vertical plane of the said branches.
Claim 6
Dependent Claim
72 words
Relay according to any one of claims 1 to 4, characterized in that it also contains a housing (12) in which the said yoke (6) is inserted, closed by a cover (14) in which a recess (54) is formed whose faces (58 and 68) co-operate with the faces (32 and 70) opposite the said permanent magnet in order to define the position of the latter in relation to the said vertical branches.
