A damping chamber is formed in a pressure relaxation device connected to a high pressure fuel pipe. Valve bodies are provided at openings of partitions, and a spring force is applied to the valve bodies by a spring in a valve closing direction. When a high pressure portion reaches an inlet of the damping chamber, the valve body opens to hold and absorb the high pressure portion in the damping chamber.

Eine variable Ventilsteuerzeit-Vorrichtung für eine Verbrennungskraftmaschine umfass einen variablen Ventilsteuerzeit-Mechanismus (30), der einen Ventiltakt ändert; und einen Phasenbegrenzungsmechanismus (40), der eine Drehphase zwischen einem Gehäuserotor und einem Drehschieberrotor bei einer Zwischenphase (PM) arretiert. Der Phasenbegrenzungsmechanismus (40) bringt einen ersten Begrenzungszapfen (51) in Eingriff mit einer ersten Eingriffsnut (60) und einen zweiten Begrenzungszapfen (71) in Eingriff mit einer zweiten Eingriffsnut (80), um den Gehäuserotor mit dem Drehschieberrotor zu verriegeln. Eine der der Verzögerungsseite zugeordnete Seitenfläche (83A) eines Eingriffslochs (83) ist derart gestaltet, dass sie befähigt ist, einen Abstand zwischen dem zweiten Begrenzungszapfen (71) und der der Verzögerungsseite zugeordneten Seitenfläche (83A) einzustellen, wenn der erste Begrenzungszapfen (51) mit einem ersten Voreilendabschnitt (62A) in Eingriff ist. A variable valve timing device for an internal combustion engine includes a variable valve timing mechanism (30) that changes a valve timing; and a phase limiting mechanism (40) which locks a rotational phase between a housing rotor and a rotary vane rotor at an intermediate phase (PM). The phase limit mechanism (40) engages a first limit pin (51) with a first engagement groove (60) and a second limit pin (71) with a second engagement groove (80) to lock the housing rotor with the rotary vane rotor. One of the side surfaces (83A) of the engagement hole (83) assigned to the delay side is designed such that it is able to set a distance between the second limiting pin (71) and the side surface (83A) assigned to the delay side when the first limiting pin (51) engages a first leading end portion (62A).

Control apparatus for internal combustion engine

An IIS system (2) that performs control related to intermittent stopping of engine operation by idling stop control is applied to an internal combustion engine including a VVT mechanism (6) that makes the valve timing of an engine valve variable and has an intermediate lock mechanism (18) that mechanically locks the valve timing at an intermediate lock position between a most retarded position and a most advanced position. The IIS system (2) is configured to inhibit the engine operation from being intermittently stopped at the occurrence of a failure of the VVT mechanism (6) to avoid the internal combustion engine from being prevented from being restarted after the intermittent stop depending on the occurrence of the failure of the VVT mechanism (6).

Engine with intake valves operated by camshaft

In a V-type 8-cylinder engine in which the torque for rotating an intake camshaft is higher when intake valves of a #1 cylinder and a #3 cylinder in a left bank are closed, respective noses of a cam (510) for opening and closing the intake valve of the #1 cylinder and a cam (530) for opening and closing the intake valve of the #3 cylinder are each formed at a phase position displaced by X° (X > 0) in the advance direction further from the phase position displaced in the advance direction by 90° with respect to the nose of a cam for opening and closing the intake valve of a cylinder fired after a delay of 180° in crank angle.

Magnetic tape cassette

A magnetic tape cassette for use in an apparatus having a light source (P) and a light sensor (S 1, S 2 ) for detecting a tape end by the difference of light transmittance of a tape (T). The magnetic tape cassette (AA, BB, CC) is composed of a light-shielding member (a through r) crossing a light path (L 1, L 2 ) for detecting the tape end by the difference of light transmittance of the magnetic layer portion and the leader portion to keep the light transmittance within the predetermined value even the tape (T) is thinner and has a higher light transmittance.
