Abstract

The valve comprises a flat, rectangular body attachable to the drain fittings of crankcases by an attachment fitting having passages which allow flow through the fitting into the body. The body has an outlet port in one of its sides. The port is opened and closed by a seal attached to a slider which slides on bolts extending from the side having the port. The slider is forced toward the port by coil springs on the bolts and moved away from the port to open the valve by tension applied by the core wire of a Bowden cable. The cable extends from a header piece held between the springs on the bolts and the bolt heads to an operating mechanism attached to a readily accessible point on the vehicle in which the crankcase is used. A lever, pivoted to the base of the operating mechanism, is operable to apply tension to the core wire of the cable to open the valve and can be moved over center to hold the valve open. Moving the lever back over center allows the springs to close the valve.

Claims

1. A remotely operable valve attachable to an internally threaded fitting, said valve comprising:

a body having two parallel, planar faces and at least one side, a cavity, a port in said at least one side opening into said cavity and a cylindrical hole through said body and said cavity, said hole having a first diameter and an axis perpendicular to said two planar faces, said body further having two threaded holes extending into it and having parallel axes essentially parallel to said planar faces, said threaded holes being adjacent to said port,

two bolts having heads, shanks and threaded ends, said threaded ends being threaded into said threaded holes whereby said shanks are parallel to each other,

a header piece having first and second holes, sized and oriented whereby said header piece is installable on and is installed on said shanks adjacent to said heads,

a slider having a slider face and third and fourth holes sized and oriented perpendicular to said slider face and whereby said slider is installable on and is installed on said shanks with said slider face facing said port,

two compression springs, installed one on each of said shanks of of said two bolts between said header piece and said slider, whereby said springs apply forces to move said slider toward said body,

a seal installed on said slider face whereby when said slider face is moved toward said body by said springs said seal closes said port,

apparatus for moving said slider,

features in said header piece and said slider for attaching said apparatus to move said seal away from said port against said forces applied by said springs, whereby said valve is opened, and to allow said forces applied by said springs to move said seal against said port, whereby said valve is closed,

an attachment fitting having a head, a cylindrical shank, a threaded end, a bore in said shank, said cylindrical shank having an outer surface and a second diameter such that said cylindrical shank fits in said cylindrical hole through said body, said fitting having at least one passage between said outer surface and said bore,

first and second ring shaped gaskets,

whereby with said attachment fitting inserted through said hole through said body with said first gasket between said head of said attachment fitting and one of said two planar parallel faces and said second gasket against the other of said two planar parallel faces and said threaded end of said attachment fitting threaded into said internally threaded fitting, said valve is attached to said internally threaded fitting.
