Abstract: A fluid container cover includes a cap having an outer and an inner surface. The inner surface is capable of being coupled to the fluid container. A spout includes a drinking portion, an actuation portion and a curved, distal end. The spout is capable of being actuated from a first closed position to a second open position by an external force. A flexible tube is coupled inside of the spout, and has a first end and a second end. An air venting component has a nub and a plurality of air vent holes. When the spout is in the first closed position, the flexible tube is deformed preventing flow through the spout. When the spout is actuated from the first closed position to the second open position, the curved, distal end of the spout deflects the nub allowing passage of air with the fluid container.

Abstract: The invention concerns a valve plate for a reciprocating compressor, the valve plate being made as a sintered part, having on at least one valve plate surface at least one valve seat surface (30, 31) being worked after sintering. In order to simplify the manufacturing of the valve plate, the valve plate surface has at least one defined area portion with a relatively uneven surface and at least one defined area portion with a relatively even surface.

Abstract: The invention concerns a cylinder head arrangement for a piston compressor, with a cylinder block, in which a compression chamber is formed, which is delimited on one side by a valve plate that is clamped between the cylinder block and a cylinder head cover. In order to provide a cylinder head arrangement that has a high degree of tightness and can be manufactured in a cost-effective manner, the valve plate (6) has on at least one side at least one bead (40) projecting from the valve plate surface (21) concerned.
