摘要:
A valve train device for an engine for driving a valve which opens and closes a valve opening of a combustion chamber comprises: a valve drive device comprising a drive member and driving force transmission mechanism. The drive force transmission mechanism is configured to transmit a driving force from the drive member to the valve. The drive force transmission mechanism comprises a transmission portion configured to transmit the driving force from the drive member to the valve and a variable portion configured to continuously change a state of the transmission portion to thereby continuously change an opening duration of the valve or the amount of valve lift. At least part of the variable portion is positioned within in the transmission portion.

A valve drive mechanism for actuating a valve of an internal combustion engine includes a cam member with a cam surface having a first portion and a second portion. A roller is configured to rotate and contact the first portion of the cam surface when the valve is in a closed position and the second portion of the cam surface with the valve is in an open position. The cam member and the roller are configured to reciprocally move relative to each other to open and close the valve. When the roller contacts the first portion, a gap within the valve drive mechanism exists between components of the valve drive mechanism on a downstream side of a force transmission path to the valve with respect to a contact point between the roller and the cam surface. A spring member urges the roller and the cam surface into contact with each other during motion between the cam member and the roller.

A cosmetic container (10) comprises a housing assembly (1, 3, 4, 7, 9) with an annular projection (8) and a cap assembly (11, 12) with an inner cap member (12) engageable with the annular projection. The inner cap member has a wall portion (15) between upper and lower annular external swells (16, 17), which is deformed to provide air-tight engagement with the annular projection in a capped condition. The lower swell (16) comprises a plurality of spaced segmental annular projections (161) formed substantially around the outer surface of the inner cap member and one or more of dotty projections (162) positioned substantially within each space between adjacent two of the segmental annular projections. The lower swell acts as a first stopper for preventing removal of the cap assembly from the housing assembly, whereas the upper swell acts as a second stopper for preventing excessive insertion of the housing assembly into the cap assembly.

A cylinder head constructions wherein the cylinder head is comprised of a main cylinder head member that slidably supports the valves for the engine, and which has an upper peripheral edge that defines a cam chamber. At least one camshaft and the tappets associated thereby are supported by a separate cam and tappet carrier member that is affixed to the main cylinder head member. The bearing surfaces for the camshaft are formed at longitudinally spaced points and the valves for the corresponding cylinder are disposed between those points and are in parallel relation but have a large diameter and their actuating tappets have a large diameter but do not encroach on the bearing surfaces for the camshaft.

An outer body surrounds a main body and is rotatable with respect to the main body to move up and down a cosmetic holder received in the main body. An insert sleeve is coupled integrally to the upper end portion of the outer body, by welding, integral-forming or any other suitable coupling device. The main body has an annular projection on its outer peripheral surface, which rotatably and elastically contacts with a lower portion of the insert sleeve. In an embodiment, the insert sleeve has a downwardly extending tongue which may be deformed elastically and contact with the projection of the main body. The projection is spaced apart from the outer body.

The invention provides a curable composition of polychloroprene, chlorinated polyethylene or polyepichlorohydrin containing at least one metal oxide having an oxidation state of 2 to 5 valences as a curing agent and at least one accelerator of the formulaA--(S).sub.n --A'wherein S is a sulfur atom, A and A' are polyhydroxy aryl groups having 6 to 18 ring carbon atoms and n is zero or an integer of 1 to 4. The accelerators enable a satisfactory rate and state of cure with the metal oxide.
摘要:
A valve drive device for an engine include a valve for opening or closing an opening of a port to a combustion chamber, a valve drive member for opening or closing the valve and a drive shaft for driving the valve drive member. The device also includes a variable valve timing mechanism for continuously changing a working angle of the valve corresponding to an operation state of the engine by changing a state of drive force transmission from the drive shaft to the valve drive member. A variable valve clearance mechanism is configured such that a valve clearance that is defined as a gap between the valve and the valve drive member can be set at a first value during a first condition in which the working angle of the valve is large to a second different value during a second condition in which the working angle of the valve is small.
