Abstract: A valve stem seal assembly comprises an elastomeric seal having first and second radially inwardly directed sealing lips that are in intimate sealing contact with a valve stem. Also, a metal seal retainer has a first metal seal retainer portion disposed on a first top portion of the elastomeric seal. The metal seal retainer radially abuts a second top portion of the elastomeric seal and is bonded thereto, where no portion of the elastomeric seal is axially above the first metal seal retainer portion. A second metal seal retainer portion is continuous and unitary with, and perpendicular to the first metal seal retainer portion. An outer surface of the elastomeric seal is bonded to an inner surface of the second metal seal retainer portion, and no portion of the elastomeric seal is radially outward of the second metal seal retainer portion.

Abstract: A valve stem seal exhibits superior workability of mounting of a reinforcing ring to a valve stem guide and enables the reinforcing ring to be fixed to the valve stem guide in a stable manner. A reinforcing ring is mounted to a valve stem guide by fitting a cylindrical portion to the valve stem guide from a side opposite to an inward flange portion. The cylindrical portion includes a slit extending linearly in a circumferential direction and a locking protrusion that is provided on a side opposite to the inward flange portion with respect to the slit and that is to be locked by a locking recess formed in the valve stem guide. The locking protrusion is constituted by a curved portion that is gradually recessed radially inward from the side opposite to the inward flange portion with respect to the slit to a position that reaches the slit.

Abstract: A valve seal removal tool includes: an elongated, threaded rod having a stopper mounted at a proximal end of the rod and a collet connected to a distal end of the rod having an inner circumference capable of being fitted over an outer circumference of a valve seal; a collet holder movable along the longitudinal axis of the rod, and having an inner circumference capable of being fitted over an outer circumference of a proximal end of the collet; a threaded nut coupled to the rod; and a slide hammer slidable along the rod and having a proximal end that opposes the stopper and is operable to slidably contact the stopper. Tightening the nut in a distal direction of the rod causes the nut to contact the collet holder, forcing the collet holder to move over a portion of the collet which compresses the collet.

Abstract: An exhaust valve assembly for a two-stroke internal combustion engine has a valve actuator having a first pressure chamber and a second pressure chamber, and a valve operatively connected to the valve actuator. The first and second pressure chambers are adapted for selectively receiving one of a first pressure and a second pressure. The first pressure is higher than the second pressure. The valve actuator moves the valve between at least a first valve position and a second valve position. The valve actuator moves the valve to the first valve position when the first pressure is supplied to the first pressure chamber and the second pressure is supplied to the second pressure chamber. The valve actuator moves the valve to the second valve position when the second pressure is supplied to the first pressure chamber and the first pressure is supplied to the second pressure chamber.
