A hydraulic damper (2) includes at least one spring valve assembly (28b, 28c) having a body (231, 261) provided with through flow channels (282), at least one deflectable disc (281) covering these through flow channels (282), and a supporting member (285, 285c) fixed to an axial member for clamping the at least one disc (281) at the inner circumferential part thereof. A spring seat (283b, 283c) is disposed around the supporting member (285, 285c) and abuts the at least one deflectable disc (281) in at least one radial position (2831, 2832) at the outer circumferential part thereof. A spring (284) is preloaded between the spring seat (283b, 283c) and the supporting member (285, 2851c). The spring seat (283b, 283c) includes at least one axial projection (2833b, 2833c) perimetrically engaging the at least one disc (281), and a circular gap (286) is provided between the spring seat (283b, 283c) and the supporting member (285, 2851c).
