摘要： A valve assembly is disclosed for use in conjunction with a replaceable filter cartridge system. The valve assembly includes a head member having an interior valve chamber defining a central axis, and inlet and outlet passages extending parallel to and communicating with the interior valve chamber. The valve assembly further includes a valve member having an inlet path and an outlet path, adapted for rotation within the interior valve chamber of the head member between a filter position wherein the inlet path of the valve member is in communication with the inlet passage of the head member and a bypass position wherein the inlet path of the valve member is out of communication with the inlet passage of the head member. The valve assembly further includes a seal member seated in an upper surface of the valve member and positioned to seal against an opposing surface of the interior valve chamber. The seal member sealingly isolates untreated and treated fluid streams flowing through the inlet and outlet paths of the valve member, respectively, when the valve member is in the filter position, and sealingly isolates the inlet and outlet passages of the head member from the atmosphere when the valve member is in the bypass position to permit fluid to flow therebetween.

摘要： A pump dispenser has a nozzle body on which is rotatably disposed a nozzle cap having two orifices which selectively align with a swirl chamber formed in the front end of the body. One orifice is formed with a surrounding cup-like structure to retain the last drop of liquid after discharge. The other is formed with a pair of diagonal parallel ribs on opposite sides of the orifice to effect an elongated narrow landing pattern for the spray.

摘要： An additive dispensing apparatus for a fluid system is disclosed which includes a head having a body portion adapted and configured for fluid communication with the fluid system and having a flow path extending therethrough. A fluid inlet portion of the flow path defines a relatively high pressure region and a fluid outlet portion of the flow path defines a relatively low pressure region. A canister is operatively associated with the body portion and structure is provided for facilitating fluid communication between the fluid inlet portion and the interior of the canister. A collapsible container is disposed within the canister for containing a liquid additive for dispensement into the fluid system and structure is provided for facilitating fluid communication between the collapsible container and the fluid outlet portion, whereby the differential pressure between the interior of the canister and the interior of the collapsible container effectuates a proportional dispensement of liquid additive into the fluid system.

摘要： An ink containment and dispensing device for an ink-jet printer is provided with a main reservoir in the form of a flexible pouch, which is typically maintained at ambient pressure. The main reservoir is coupled to a variable volume chamber via a one-way valve which allows the flow of ink from the reservoir to the chamber and prevents the flow of ink from the chamber to the reservoir. The chamber is coupled to a fluid outlet, which is normally closed to prevent the outward flow of ink. However, when the ink supply is installed in a printer, the fluid outlet establishes a fluid connection between the chamber and the printer. The chamber is part of a pump provided with the ink supply that can be actuated to supply ink from the reservoir to the printer. The pump has a linearly acting pumping member and a flexible diaphragm that overlies the pumping member, the diaphragm being impervious to the transmission of oxygen and moisture therethrough to prevent degradation of the ink within the chamber. The flexible pouch is contained within a rigid, outer shell having an opposed pair of shorter sides interspersed with an opposed pair of longer sides, and the shorter sides of the shell, in the region of the closed end of a cup-shaped shell, are configured for grasping and for identifying the location of the closed end of the shell.
摘要翻译： 用于喷墨打印机的油墨容纳和分配装置设置有柔性袋形式的主容器，其通常保持在环境压力下。 主储存器通过单向阀连接到可变容积室，该单向阀允许墨从储存器流到腔室并防止墨从腔室流到储存器。 腔室联接到流体出口，流体出口通常是关闭的，以防止墨水向外流动。 然而，当墨水供应安装在打印机中时，流体出口在腔室和打印机之间建立流体连接。 该室是设置有墨水供应源的泵的一部分，其可以被致动以将油墨从储存器供应到打印机。 泵具有线性作用的泵送构件和覆盖在泵送构件上的柔性隔膜，隔膜不透过氧气和湿气的透过，以防止室内油墨的劣化。 柔性袋包含在具有相对的一对较短侧面的相对的一对较长侧面的刚性外壳中，并且在杯形壳体的封闭端的区域中壳体的较短边是 构造成用于抓住并识别壳体的封闭端的位置。

摘要： A pump dispenser has a body defined by a top wall and a front end and a nozzle cap rotatably mounted on the body. The cap, which must be rotated for the nozzle to operate, has an opening in a side wall thereof adjacent the front end. An elongate blocking tab has a rear portion unitary with and connected to said top wall, and a middle portion extends forwardly from the rear portion and is disposed in the opening in the nozzle cap. The tab also has a forward finger-grippable portion extending forward from said middle portion. The middle portion, by being in the opening, prevents rotary movement of the nozzle cap until the blocking tab is torn from the top wall.
