摘要： A hydraulic lash adjuster having a reduced number of elements, yet capable of suppressing air from infusing into a high-pressure chamber (28). A plunger (14) is slidably fitted in a body (13). A reservoir (24) is formed in the plunger (14). The plunger's head portion (19) is formed with a communication hole (25) for communicating its interior with its exterior. A high-pressure chamber (28) is formed in the body (13) and between the plunger's bottom (20) and the bottom of the body (13). An oil supply hole (40) is formed in the peripheral wall (21) of the plunger. A valve mechanism (42) is provided at the plunger's bottom (20), between the body (13) and the plunger (14) via a return spring (41). Provided on the inner periphery of the plunger (14) is an inclined area (51b), subjected to impingement of oil jet ji ejected from the oil supply hole (40) and serving as an impingement area, such that the impingement area (51b) is more inclined to fall in the direction of the ejected oil as the inclined area (51b) nears the plunger's head portion (19).

摘要： [Problems]
To provide a method of friction welding and an apparatus of friction welding in which a length of time for manufacturing one product is reduced as much as possible regardless of the dimension errors of works.
[Means of solving problems]
The fast forwarding distance Lx1 is calculated for the fast forwarding by using the results of measuring the dimensions of works W1, W2 under the condition of the constant slowly forwarding distance Lx2, Thereby, for the work of a legitimate dimension and even for the work having a dimension smaller than the legitimate dimension, the elongation of the slowly forwarding distance is prevented compared with the work having the longer dimension than the legitimate dimension, and the relative proportion of the fast forwarding distance Lx1 is increased by making shorter the specified slowly forwarding distance.

摘要： To provide a hollow poppet valve having an improved heat reduction effect. In a hollow poppet valve (10) having a valve head (14) and a stem (12) integral with the valve head (14), the hollow poppet valve (10) is formed with an internal cavity S that extends in the valve head (14) and the stem (12). The internal cavity S is charged with a coolant (19) and an inert gas. The internal cavity S has a generally disk-shape internal cavity S1 and an internal stem cavity S2 formed in the stem (12) and connected to the internal valve head cavity S1 at a right angle. During a reciprocal motion of the valve (10), a vertical convective flow of coolant (19) along the axis L of the valve (10) is established at least in the internal valve head cavity S1, thereby enhancing its heat reduction effect.
