Embodiment Construction

[0026] image 3 is a perspective view of a lubrication system 100 using the integrated serial progressive distribution valve 102 of the present invention, wherein the integrated serial progressive distribution valve 102 has four pistons and eight outlets. Lubrication system 100 also includes automatic fluid source 104 , manual fluid source 106 , hoses 108A and 108B, and lubrication target 110 . Valve 102 includes an integral valve block 112 , piston tables 114A- 114D , outlets 116A- 116G , and inlet 118 . Manual fluid source 106 is connected to inlet 118 using any suitable fitting. For example, inlet 118 may include a grease gun nozzle, and manual fluid source 106 may include a grease gun. Alternatively, valve 102 may be connected to an automated fluid source 104 such as a large output pump that provides a larger volume of fluid at a higher pressure.

[0027] Valve 102 includes a plurality of pistons disposed within lands 114A-114D that provide outputs to outlets 116A-116G. ...

Abstract

A series progressive divider valve comprises a valve body and pistons. The valve body comprises a fluid inlet, piston bores, outlet bores, porting and undercuts. The fluid inlet extends into an exterior of the valve body. The piston bores extend through the valve body from a first end to a second end. Each piston bores includes a piston. The outlet bores extend into the valve body, each outlet bores comprises a first set of outlet bores and a second set of outlet bores. The porting forms a plurality passageways connecting the piston bores to each other and with the outlet bores such that when high pressure fluid is applied to the inlet each of the pistons reciprocates from the first end to the second end in sequence. An undercut is located at an intersection between each passageway and piston bore.

Description

technical field [0001] The present invention generally relates to series progressive dispensing valves. More specifically, the present invention relates to fittings for plugging outlet ports so that fluid may be directed progressively in series to the next outlet port. Background technique [0002] Serial progressive distribution valves have long existed in the prior art and include mechanisms for dividing a single steady input of pressurized fluid into multiple distributed bursts. Thus, fluid is delivered to the valve body at a single inlet port and delivered under pressure of the fluid to a plurality of separate outlet ports by periodic operation of the piston array or sleeve. The valve output is continuously cycled in predetermined progressions according to the movement of the piston array. For example, a conventional tandem progressive dispensing valve includes an array of pistons in which the central axes of all pistons are arranged in a single plane. The outlets for...
