摘要： A pump includes a collar, a cylinder and an elastic valve. The collar includes a wall, a tubular insert extending in the wall, and a connective portion formed between the wall and the tubular insert. The cylinder includes first and second open ends, first and second chambers respectively in communication with the first and second open ends, and a neck in communication with the first and second chambers. The elastic valve includes a ring, a plug extending in the ring, and elastic strips formed between the plug and the ring so that the plug is movable relative to the ring. The tubular insert is inserted in the first chamber via the first open end when the cylinder is connected to the wall, and the plug normally blocks the neck to form a first check valve when the elastic valve is connected to the second chamber.

摘要： An adjustable pump includes a ring connected to an open end of a container, a cap rectilinearly movable relative to the ring to dispense fluid from the container, and a quantity-adjusting unit that includes a limiting element and a knob. The limiting element is adapted for contacting the cap and hence limiting the rectilinear movement of the cap relative to the ring. The limiting element is rectilinearly movable relative to the ring to adjust a stroke of the movement of the cap relative to the ring. The limiting element includes at least one boss. The knob is rotatable relative to the ring around the limiting element. The knob includes at least one helical groove that receives the boss so that the limiting element is moved relative to the ring as the knob is rotated relative to the ring.

摘要： A nozzle includes a ring, a tube, a piston and a sheath. The ring includes an upper portion and a lower portion. The tube extends in the ring. The piston is connected to the tube and partially located out of the ring. The sheath is made of metal and includes a first annular flange at an end and a second annular flange at another end. The sheath is arranged around the ring. The first annular flange is placed against the upper portion of the ring and the second annular flange is placed against lower portion of the ring when sheath is provided around the ring. Thus, the sheath is kept on the ring without the use of any adhesive.
摘要翻译：喷嘴包括环，管，活塞和护套。环包括上部和下部。管在环中延伸。活塞连接到管并且部分地位于环之外。护套由金属制成，并且在另一端包括在端部的第一环形凸缘和第二环形凸缘。护套安置在戒指周围。第一环形凸缘抵靠环的上部设置，并且当护套设置在环周围时，第二环形凸缘抵靠环的下部放置。因此，护套保持在环上，而不使用任何粘合剂。
