Speed limiter in an elevator installation

Speed ​​limiter (17, 17a, 17b) for an elevator installation (100), in that the speed limiter (17,17a, 17b) comprises: - at least one wheel speed limiter (18, 18a, 18b) with a first cam disc (19, 19a, 19c) witha first control curve (48a) with elevations (40a-40h) and with at least one second cam disc (19b, 19d) with a second control curve (48b ) with elevations (40a'-40h '); - a first mass (26, 26a, 26d), which rolls with a first roller (28, 28a, 28d) on the first decontrol curve (48a), so that the first mass (26, 26a, 26d) takes a first oscillatory movement algirar wheel speed limiter (18, 18a, 18b), and - at least a second mass (26b, 26c), which rolls with a second roller (28b, 28c) on segundacurva control (48b) so that the second mass (26b, 26c) performs a second deoscilacion movement round the wheel speed limiter (18, 18a, 18b), wherein the first curvade control (48a) and the second control curve (48b ) having a phase shift (PHV).
