摘要： An inverted, displacer type piston pump for metering and dispensing liquids in which the cylinder is located beneath the piston and reciprocated via an actuator below the cylinder, and where the piston is held fixed. The liquid ingress and egress to and from the cylinder of the pump is via a cylindrical port through the piston along its cylindrical axis. The pump is designed so that liquid product loss through the pump is prevented without the use of elastomeric or compliant seals in the liquid contact product areas of the pump. In addition, the pump cylinder is capable of being positioned via its reciprocating actuator such that all of the liquid product contact parts are open and accessible to cleaning and sterilizing fluids which may be introduced into the pump through the liquid product supply port of the pump, thereby enabling cleaning and sterilization of the pump without its disassembly. Several embodiments of externally mounted externally operated poppet type valves designed to work in conjunction with the aforesaid or similar pumps are also indicated in which because of no sliding contact between the valve components, there is very little valve wear and a consequently a lower risk of product contamination from particulates. In addition all of the embodiments of the valves permit cleaning and sterilization of liquid product contact surfaces through the use of the aforementioned cleaning and sterilizing agents, without disassembly of the valves. Further, one embodiment of the valve also has a `suck back` feature within it, so that when the valve shifts from its open to its closed position, a small amount of the liquid product contained in the nozzle and discharge line is pulled back into the valve.
摘要翻译：用于计量和分配液体的倒置的置换器型活塞泵，其中气缸位于活塞下方并通过气缸下方的致动器往复运动，并且活塞保持固定。进出泵的液体入口和出口通过圆柱形端口沿其圆柱轴线通过活塞。该泵被设计成使得在泵的液体接触产物区域中不使用弹性体或柔性密封件来防止通过泵的液体产物损失。此外，泵筒能够通过其往复式致动器定位，使得所有的液体产品接触部分是开放的并且可以通过泵的液体产品供给口引入到泵中的清洁和灭菌流体，从而能够在不拆卸的情况下对泵进行清洁和灭菌。还指出了设计成与上述或类似泵一起工作的外部安装的外部操作的提升阀的几个实施例，其中由于阀部件之间没有滑动接触，因此阀的磨损非常小，因此产品的风险较低颗粒污染此外，阀的所有实施例都允许通过使用上述清洁和灭菌剂来清洗和灭菌液体产物接触表面而不拆卸阀。此外，阀的一个实施例也在其内部具有“吸回”特征，使得当阀从其打开位置移动到其关闭位置时，将少量包含在喷嘴和排出管线中的液体产品拉回到阀门。

The flow control system (122, 220) includes a non-return valve (124, 230) and an actuation mechanism (128, 242). The non-return valve (124, 230) have a closing member (126, 232) movable between an open position and a closed position to allow a unidirectional fluid flow and the actuation mechanism (128, 242) have an actuation element (130, 244) movable between an operative position and an inoperative position with respect to the closing member (126, 232). In the operative position, the actuation element (130, 244) applies a counteracting force (CF) to move the closing member (126, 232) to the open position and the actuation element (130, 244) is biased towards the operative position.

摘要： The present invention is a wireless electronic control device, primarily intended to be attached to the impulse valve of a Hydraulic Ram Pump (‘HRP’), enabling remote automatic and manual management of the HRP. The Electronic Ram Pump Controller (‘ERPC’) may be used to control the HRP, through the restriction of the fluids entering/or exiting the pump. In the presented form, the Impulse Valve Manager (‘IVM’), attaches to an impulse valve and restricts, to a varying degree, the aperture size of the impulse valve. Through this control mechanism the HRP may be sealed, started, or tuned—either remotely by a user or automatically through the ERPC's automated systems. The presented version can be augmented with valve actuation and sensing of the impulse cycle. The ERPC may be retrofitted or incorporated into the design of a new HRP.

摘要： A pump assembly with valve-seat interface architecture configured to extend the life of pump components and the assembly. A valve of the pump assembly is equipped with a conformable valve insert that is configured with a circumferential component having the capacity to reduce the radial strain of its own deformation upon its striking of a valve seat at the interface within the pump assembly. The circumferential component may include a concave surface about the insert, a rounded abutment at the strike surface of the insert, or a core mechanism within the insert that is of greater energy absorbing character than surrounding material of the insert. Additionally, the valve seat itself may be configured for more even wear over time and equipped with a conformable seat insert to reduce wear on the valve insert.

摘要： A valve for causing pulsatile flow in a multi-piston plunger pump includes a valve poppet, a valve seat, and a spring biasing the valve poppet against the valve seat; and a mechanism holding the valve poppet in an open position, thereby producing pulsatile flow from the pump. The mechanism includes a magnet and an adjustment mechanism for moving the magnet toward and away from the valve poppet. When the magnet is moved toward the valve poppet, the magnet attracts the poppet away from the valve seat, and when the magnet is moved away from the valve poppet, the magnet releases the poppet. The spring then biases the poppet against the valve seat in a closed position.

摘要： Apparatus and method for releasing a stuck inlet check valve of a paint pump including a solenoid connected to the check valve with a pusher element which momentarily displaces a moveable element such as a ball in the check valve to break any adhesion between the movable element and a valve seat. A control provides a single pulse of energy to the solenoid each time power is applied to the pump. The control includes an SCR connected between a full wave rectifier and a coil of the solenoid, with gate current removed from the SCR to commutate the SCR after a predetermined time interval after power is applied.
