A leak identification and containment device (10, 48, 64) is provided which is designed for application to a valve assembly (12) including a conduit (16) and a valve (18) having an operating handle (20) and an outlet (22). The device (10, 48, 64) includes a flexible bag (24, 50, 66) formed of synthe
A leak identification and containment device (10, 48, 64) is provided which is designed for application to a valve assembly (12) including a conduit (16) and a valve (18) having an operating handle (20) and an outlet (22). The device (10, 48, 64) includes a flexible bag (24, 50, 66) formed of synthetic resin material which is at least translucent (and preferably substantially transparent) with a valve-receiving opening (30, 52) and an absorbent lining (34) on the inner surfaces of the bag (24, 50, 66). In use, the bag (24, 50, 66) is disposed over the valve assembly (12) including handle (20) and outlet (22) and a cinch strap (34, 54) is used to tighten the bag (24, 50, 66) about the conduit (16). The absorbent lining (34) is of a color which contrasts with that of material which may leak from the valve assembly (12), so that the device (10, 48, 64) gives a visual indication of leakage. In a preferred embodiment, the valve assembly extends from a transformer tank (10), the bag (24, 50, 66) is formed of substantially transparent reinforced polyethylene material, and the bag lining (34) is white in color.

A two-cycle internal combustion engine which is constructed such that one or more pairs of schnurle type scavenging passageways, each allowing a combustion actuating chamber disposed above a piston placed in a cylinder to be communicated with a crank chamber, are symmetrically provided on both sides of a longitudinal section which imaginatively divides an exhaust port into two equal parts, thereby enabling air to be introduced into the scavenging passageways and also enabling air-fuel mixture to be introduced into the crank chamber; and that in the descending stroke of the piston the exhaust port is opened at first, and then, the scavenging port which is disposed at a downstream end of the scavenging passageway is opened, thereby enabling air to be introduced via the scavenging passageway into the combustion actuating chamber prior to the introduction of air-fuel mixture into the combustion actuating chamber; said internal combustion engine being characterized in that said one or more pairs of schnurle type scavenging passageways are respectively provided, near the end portion thereof located close to the crank chamber, with a throttled portion, wherein an effective cross-sectional passage area of the throttled portion is set to such that a required quantity of air-fuel mixture can be fed to the combustion actuating chamber following the introduction of air thereto. 6. The two-cycle internal combustion engine according to claim 4, wherein said paired scavenging passageways are combined with each other at the portion thereof located close to the crank chamber to thereby enlarge the volume thereof, and are communicated with the crank chamber via a common throttled portion. 7. The two-cycle internal combustion engine according to claim 6, wherein said scavenging passageways are provided respectively with an air inlet passageway for introducing air therein, and the air inlet passageway is provided with an air check valve. 8. The two-cycle internal combustion engine according to claim 4, wherein said scavenging passageways are provided respectively with an air inlet passageway for introducing air therein, and the air inlet passageway is provided with an air check valve. 9. The two-cycle internal combustion engine according to claim 5, wherein said paired scavenging passageways are combined with each other at the portion thereof located close to the crank chamber to thereby enlarge the volume thereof, and are communicated with the crank chamber via a common throttled portion. 10. The two-cycle internal combustion engine according to claim 9, wherein said scavenging passageways are provided respectively with an air inlet passageway for introducing air therein, and the air inlet passageway is provided with an air check valve. 11. The two-cycle internal combustion engine according to claim 10, wherein the volume of said scavenging passageways is set to such that it is equal to or slightly smaller than the quantity of air to be introduced in advance. 12. The two-cycle internal combustion engine according to claim 9, wherein the volume of said scavenging passageways is set to such that it is equal to or slightly smaller t
