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.
