Abstract: An electric shifting mechanism for a fluid-powered diaphragm pump is provided. The shifting mechanism includes a controller programmed to switch the pump at timed intervals, a solenoid valve and an end of stroke valve. The end of stroke valve translates the pneumatic end of stroke signals generated by the pilot valve into electric signals. The electric signals are then transmitted to the controller. The controller sends timed switch signals to an operator of the solenoid valve. The operator shifts the solenoid valve which transmits a pilot signal generated from the compressed air supply to either the right or the left pilot signal port of the main air valve. The main air valve does not receive pilot signals directly from the pilot valve but, in turn, receives its pilot signals from the solenoid valve which receives signals from the controller. The controller receives end of stroke signals from the end of stroke valve which translates the pneumatic signals generated by the pilot valve into electric signals. The controller than compares the end of stroke signals received from the end of stroke valve with the pre-programmed timed intervals and provides an indication or an alarm if the controller is programmed to shift the pump before the pump reaches the end of its stroke. The solenoid valve and end of stroke valve may be easily incorporated into existing pumps.

Abstract translation: 提供一种用于流体动力隔膜泵的电动换档机构。 换档机构包括被编程为以定时间隔切换泵的控制器，电磁阀和行程末端阀。 行程阀的末端将先导阀产生的行程信号的气动端转换为电信号。 然后将电信号传送到控制器。 控制器向定时开关信号发送电磁阀的操作员。 操作者将从压缩空气供给产生的导频信号发送到主空气阀的左右导频信号端口的电磁阀。 主空气阀不直接从先导阀接收导向信号，而是接收来自接收来自控制器的信号的电磁阀的导频信号。 控制器从行程阀的末端接收行程信号结束，将先导阀产生的气动信号转换为电信号。 控制器比较从行程阀端部接收的行程信号的结束与预编程的定时间隔，并且如果控制器被编程为在泵达到其行程结束之前移动泵，则提供指示或报警。 电磁阀和行程阀的末端可以容易地并入现有的泵中。

Abstract: A fluid powered diaphragm pump with an adjustable stroke is provided. The stroke of the pump is adjusted by providing an inner diaphragm plate assembly that includes a retractable piston. The piston is biased towards the inner plate by one or more standoffs that attach the piston to the plate. The bias of the piston is overcome by pressurized fluid that is communicated to a chamber defined by the piston and the inner plate. The fluid may be communicated to the chamber through the diaphragm rod. The inner diaphragm plate assemblies of both diaphragm chambers may be connected to different pressurized fluid supplies there enabling the stroke or capacity of the two diaphragm chambers to be controlled independently. As a result, the stroke or capacity of the two diaphragm chambers may differ.

Abstract: A check ball valve seat assembly for a diaphragm pump is provided that includes an annular carrier plate which accommodates an annular seat member. The assembly is sandwiched between two components of a diaphragm pump, such as a component for providing a retainer for the ball component of the check valve and a retainer providing a backing support for the check ball valve seat assembly. The annular seat member sealingly engages the ball retainer component and the support component of the pump which prevents the fluid that is being pumped from coming into contact with the annular carrier plate.

Abstract: A valve assembly including a valve housing with a spool valve mounted for reciprocation within the valve housing, with a detent mechanism disposed on the spool valve and the valve housing for selectively locking the spool valve against reciprocal movement, and for providing an externally observable indicator of valve position. In an illustrative embodiment, the detent assembly of the present invention includes at least one detent pin disposed on the spool valve, with at least one guide flange disposed on the valve housing. The guide flange is adapted to at least partially surround the detent pin. At least one retaining clip is provided which is adapted for insertion through the guide flange to engage the detent pin. When the retaining clip is inserted through the guide flange and in engagement with the detent pin, the spool valve is locked into a predetermined stationary position, and cannot reciprocate. The detent assembly can also include at least one detent pad disposed in the valve housing which is capable of operative engagement with the detent pin in order to provide a physical indication of the position of the spool valve. The detent pad can be provided in the form of an elastomeric washer disposed at one end of the valve housing. The elastomeric washer is provided with a central aperture having a diameter that is substantially less than the outer diameter of the detent pin of the spool valve. The detent pin can be provided with a recessed groove which interacts with the detent pad to provide a tactile indication that the spool valve has reached a predetermined position.

Abstract: The fluid-operated, double diaphragm pump of the invention includes a central housing block having opposed side faces, and a pair of diaphragm housing end sections secured to opposite sides of the central housing block. The diaphragm housings define a pair of enclosures having a common central axis. Mounted in each of the diaphragm housings is a diaphragm that serves to divide each enclosure into an inner pumping chamber, defined by a side face of the housing block and the diaphragm, and a drive chamber defined by the opposite side of the diaphragm and, at least in part, by the inner surface of the respective end section. The central housing block defines inlet and discharge passages for the inner pumping chambers, the flow of material through the passages being controlled by one-way check valves associated therewith. In one embodiment of the invention, the pump also includes a connecting arrangement disposed externally of the pumping chambers. The connecting arrangement links the diaphragms to one another for simultaneous flexing movement. A valve assembly is associated with the connecting arrangement, and alternately supplies drive fluid under pressure to the fluid drive chambers, in response to movement of the connecting arrangement. A source of operating fluid pressure and a control valve system are also provided. In another, preferred embodiment, the modular double-diaphragm pump of the present invention includes separate drive mechanisms for each of the flexible diaphragms. Such configuration further reduces the number of parts required for the pump, thus greatly simplifying and facilitating ease of assembly and disassembly of the pump. This configuration also allows the diaphragms of any number of pumps to be controlled independently of one another, thus greatly enhancing the versatility of the system.
