Embodiment Construction

[0030] [the whole frame]

[0031] Such as figure 1As shown, a valve timing control device 1 according to one embodiment includes an outer rotor 3 (driving side rotating member), a front plate 4, and an inner rotor 5 (driven side rotating member). The outer rotor 3 and the front plate 4 rotate synchronously with the crankshaft of the engine. The inner rotor 5 is coaxially arranged with the outer rotor 3 . The outer rotor 3 rotates synchronously with the camshaft 8 for opening and closing the engine valves. The inner rotor 5 is integrally arranged on the end of the camshaft 8, the camshaft 8 constitutes the rotating shaft of the cam, and the cam is used to control the opening and closing of the intake valve and the exhaust valve of the engine. The recess 14 is formed on the radial inner side of the inner rotor 5 (the axis side of the camshaft 8 ) so as to open toward the opposite side of the camshaft 8 (to open toward the front plate 4 ). Furthermore, a fixing hole 12 is for...

Abstract

A valve timing control apparatus (1) includes a driving side rotational member (3), a driven side rotational member (5), an advanced angle chamber (6a) and a retarded angle chamber (6b), and a fluid control valve portion (2) arranged orthogonally relative to the camshaft (8) at an opposite side of the camshaft (8) so as to dispose the driving side rotational member (3) and the driven side rotational member (5) between the fluid control valve portion (2) and the camshaft (8), the fluid control valve portion (2) including a first linearly moving member (25) linearly moving in an orthogonal direction relative to the camshaft (8), thereby controlling supplying and discharging of a fluid relative to the advanced angle chamber (6a) and the retarded angle chamber (6b).

Description

technical field [0001] The present disclosure relates to a valve timing control device for controlling a relative rotational phase of a driven side rotating member with respect to a driving side rotating member which rotates synchronously with a crankshaft of an internal combustion engine. Background technique [0002] A well-known valve timing control device disclosed in JP2004-340142A includes: a hydraulic chamber formed at one of the driving side rotating member and the driven side rotating member; and a partition formed at the driving side rotating member and the driven side rotating member. The other part of the rotating part of the moving side is used to divide the hydraulic chamber into an advanced angle chamber and a retarded angle chamber. The fluid supplied or discharged with respect to the advanced angle chamber or the retarded angle chamber is controlled, thereby controlling the relative rotational phase of the driven side rotational member with respect to the dr...
