Abstract
A filter for use in a distributor valve arrangement, the filter having a filter base block having an identical dimension with feeder base blocks and bolted thereto in a stacked arrangement. The filter can be located at an inlet end of the distributor valve or placed in sequence at any position within the stacked arrangement for special filtering applications. The filter has a filter block mounted to the filter base block, which has a bore therein for receiving a cylindrical screen element which is held in by an external screwed plug. On an opposite side of the filter block is provided a screwed bore for applying an indicator to sense differential pressure across the filter element to detect a clogged filter.
Claims18
A distributor valve for distributing lubrication to multiple lubrication users, comprising:
- a plurality of feeder blocks, each having a reciprocating piston for reciprocation to deliver a quantity of lubricating oil to a lubrication user, said feeder blocks arranged in a stacked arrangement attached together;
- and
- a filter block attached to said plurality of feeder blocks at a position in the stacked arrangement, said filter block comprising a bore therein closed by an external plug, and a filter element fit within said bore and contained therein by said plug, said filter block having an inlet for receiving lubricating oil and an outlet for communication of that lubricating oil into a next adjacent one of said plurality of feeder blocks, and said filter element arranged between said inlet and outlet.
A filter for use in a modular lubrication distributor valve, the distribution valve having a plurality of stacked feeder blocks, each flow connected to a lubrication user and having means for directing a preselected amount of lubrication to the user, comprising:
- a filter block mounted to said plurality of filter blocks at a position along said stack of feeder blocks, said filter block comprising a bore therein closed by an external plug, and a filter element fit within said bore and held therein by said plug, said filter block having an inlet for receiving lubricating oil and an outlet for communication of that lubricating oil into said plurality of feeder blocks, and said filter element arranged between said inlet and outlet.
A modular filter for use in a series progressive distributor valve for lubricating machinery, the distributor valve having a plurality of stacked feeder modules each having a feeder block mounted on a base block, the feeder block having a flow regulating valve therein and the base blocks having an inlet and an outlet for tube connection to a lubrication user, comprising:
- a filter block having a replaceable filter element therein and a first channel means for delivering lubricating oil through said element;
- a filter base block having an inlet and an outlet, said inlet connected to a source of lubricating oil, said outlet connected to an inlet of a next adjacent feeder base block, and second channel means for connecting said inlet to said outlet via said first channel means, said filter block removable from said filler base block, said filter base block fastened to said adjacent feeder base block.
