Abstract: An improved deactivation hydraulic lash adjuster wherein the prior art lost motion spring or springs formerly located within the body of the DHLA and below the pin housing are either omitted completely or are reduced in length, spring force, and/or number and are augmented hydraulically, allowing a shorter, more compact lifter body and reduced overall lifter length. The prior art lost motion spring chamber becomes a hydraulic chamber connected to a new pressurized oil supply gallery containing an accumulator in the engine. An embodiment having no lost motion spring and solely hydraulic lost motion return can be even shorter than a spring-hydraulic hybrid because the potential hydraulic pressure to be brought against the pin housing is not a function of the length of the lost motion chamber, which length is limited only by the required displacement of the pin housing.

Abstract: A brushless motor of a variable valve mechanism varies a actuation parameter of an intake valve of an engine. A position sensor outputs a pulse signal when the brushless motor rotates. A position counter calculates a counter value by counting edges of the pulse signal. A motor control device obtains a detection value of a motor rotational angle based on the counter value when the motor control device is in a powered state. An engine control device determines that the detection value of the motor rotational angle is displaced from the actual value when the engine control device detects that the engine is operating and the motor control device portion is in a non-powered state.

Abstract: A lash adjuster includes a plunger inserted into a body and defining a pressure chamber in the body, and a spacer. The plunger is moved axially when a working fluid flows into or out of the pressure chamber so that a volume of the pressure chamber is increased or reduced. The plunger has a bottom wall defining the pressure chamber, a peripheral wall rising from an outer periphery of the bottom wall and an outer peripheral surface having an annular groove located at a height position confined in a thickness range of the bottom wall. When fitted in the groove, the spacer has a plate width equal to a separating distance between a groove bottom and an inner peripheral face of the body to fill a gap between the body and the plunger. The spacer has a flow path through which the working fluid introduced into the pressure chamber leaks.

Abstract: OBJECTTo provide a hydraulic lash adjuster capable of retaining a large amount of hydraulic oil, in a reservoir communicated with a high-pressure chamber when the engine is stopped.MEANS FOR SOLVING THE PROBLEMA hydraulic lash adjuster including: a cylindrical body (24) having an upper open end, a closed bottom, and a second oil supply hole (27a) formed in the sidewall of the cylindrical body; and a plunger having a top end serving as a plunging end, a sidewall, a bottom end, a high pressure chamber (29) at the lower bottom, and a first oil supply hole (24b) formed in the sidewall, the plunger being slidable on the inner wall of the body. The plunger has a reservoir (28) that communicates with an external oil supply line (32) via the first oil supply hole (24b) and the second oil supply hole (27a). The lash adjuster is provided with a check valve (40a) for opening the oil supply hole (24b) by the oil pressure led from an external oil passage (32) to the oil supply hole (24b). The check valve (40a) is arranged in an annular communication passage (T) formed between the sidewalls of the plunger (26) and the body (24) for communicating the oil supply hole (27a) with the oil supply hole (24b). Leak-down oil is recycled while the engine is in operation. When the engine is stopped, the check valve (40A) closes the oil supply hole (24b). Accordingly, a large amount of hydraulic oil is stored in the reservoir (28) communicated with the high pressure chamber (29), with the oil level H in the reservoir (28) never being lower than the open end of the body (24).

Abstract: The present invention makes it possible to favorably change valve-opening characteristics of a valve using a simplified configuration without leading to an increase in the number of components and also without causing an increase of friction due to sliding, in a valve operating apparatus for an internal combustion engine in which the valve-opening characteristics of the valve are variable. A changeover mechanism for switching the connection/disconnection of rocker arms disposed between cams and a valve is provided. When a slide pin reaches a displacement end in the retreating direction of changeover pin, the biasing force of a return spring acting on changeover pins is received by an engaging part between a notch part provided in the slide pin and a lock pin in a state separated from a camshaft.
