One-pack room temperature-curable sealant composition for automobile

A plate-shaped gasket is inserted between a plurality of parts with an edge of the plate-shaped gasket offset such that portions of mutually joining surfaces of the plurality of parts to be joined to each other (a cylinder block and a cylinder head , as well as a chain cover and a sprocket casing portion in the embodiment) directly oppose each other, and a liquid gasket is filled in a gap G formed by the directly opposing portions of the plurality of parts and the offset edge (an inner peripheral edge of a chain accommodating hole ) of the plate-shaped gasket. As a result, since the thickness of the liquid gasket can be determined by the thickness of the plate-shaped gasket, it becomes unnecessary to form a recessed portion for storing the liquid gasket by machining, so that the number of manufacturing steps is prevented from increasing.

Sealing structure

A mechanism for forming a liquid-tight seal around the rotary shaft of a liquid pump having a stationary ring attached to the casing of the pump and a rotating ring attached to the rotary shaft and contacting the stationary ring. The stationary ring is formed from baked carbon, while the rotating ring is a sintered product of silicon nitride. The stationary ring has an effective seal width ratio, rp/Di, of 0.07/1 to 0.22/1, where rp is the width of the effective seal surface of the stationary ring and Di is its inside diameter.

Mechanism for forming a seal around the shaft of a liquid pump

A sealed-type lash adjuster includes a cylindrical body; a plunger received in the body and forming a chamber with the bottom of the body; and a diaphragm mounted between an open end of the body and the plunger, and forming a reservoir for hydraulic oil to be supplied to the chamber. The adjuster also includes a holder having a bushing for receiving the body with the bottom of the body engageable with a valve rocker, and the diaphragm and the open end of the body generally facing away from the combustion chamber, a reservoir for storing fluid lubricant, and a conduit for conducting fluid lubricant from the reservoir to an interior annular channel in the bushing. At least part of the thickness of the diaphragm is formed of a fluorine-bonded layer extending over the entirety of the diaphragm.

Sealed-type lash adjuster

A hydraulic oil for a sealed-type lash adjuster is engine oil based, comprising mineral oil as a principal component, and 3% or less by weight of an additive which includes at least one of an anti-oxidant, a detergent-dispersant, a rust preventative, and an anti-foaming agent.

Hydraulic oil for use in sealed-type, lash adjusters

A sealed-type hydraulic lash adjuster having a reservoir chamber holding a hydraulic oil having a molecular weight distribution substantially equal to the molecular weight distribution of the exterior oil surrounding the lash adjuster. The approximate matching of molecular weight distributions of the hydraulic oil within the lash adjuster, and the exterior oil contacting the outside of the lash adjuster ensures that the volume of oil in the reservoir chamber remains substantially constant, as the amount of hydraulic oil passing through the diaphragm of the lash adjuster from the reservoir is equal to the amount of exterior oil passing through the diaphragm into the reservoir chamber.
