Abstract: Provided is an assembly structure of a drive shaft and a swash plate in a swash plate type compressor including a housing, a cylinder block having a plurality of cylinder bores, a drive shaft rotatably supported by the cylinder block or the housing, a swash plate installed at the drive shaft to vary its tilt angle with respect to the drive shaft, and pistons reciprocally accommodated in the cylinder bores, characterized in that the assembly structure includes: a swash plate tilt support pin fixedly installed at the drive shaft to cross the drive shaft; a hinge coupling groove formed in the swash plate to be rotatably coupled to a tip of the swash plate tilt support pin in a tilted manner, and a swash plate support part formed in the swash plate to support the drive shaft. Therefore, it is possible to simplify the structure of the swash plate type compressor and reduce its own weight by omitting a lug plate or a hinge mechanism in an assembly structure of the drive shaft and the swash plate.

Abstract: A resealable cap for a drink bottle having a pump for pressurizing a liquid in the bottle and a tight sealing connection with a threaded bottle neck. The pump is a tube having a soft resinous stepped base within a cylinder which extends downward through the neck into the interior of the bottle. A seal is formed between the base of the tube and the cylinder wall. At the base of the cylinder is a valve for allowing air compressed by the soft base and tube to flow into the bottle and which is sealed shut by the higher pressure created in the bottle when the soft base is retracted. The soft base has a small expandable slit adjacent the tube and above the step forming the seal through which deforms so that air can enter the cylinder on the upstroke. The slit is compressed closed on the downstroke and prevents air from leaving so it is instead forced through the valve.
