The valve has a main housing including a tapered bore and openings in communication with an interior water retaining portion of the boat and the exterior of the boat. A spring-urged tapered valve element having a passageway therein is mounted within the tapered bore of the main housing and is rotatable between first and second positions to bring the passageway of the valve element into and out of alignment with the openings in the main housing.

Abstract: The subject valve fits into the drain fitting of crankcases and is operable by tension applied to a cable attached to it at one end. The other end of the cable is made readily accessible by attachment to a fitting attached at a convenient place to the vehicle of which the crankcase is a part. The valve is a poppet valve with a stem and is held closed by a conical compression spring. The operating cable is engaged in the valve fitting and poppet stem such that tension in the cable lifts the poppet off the valve seat to open the valve. The valve automatically closes when the tension on the cable is relieved.

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.

Abstract: A raft inflation valve, which is actuated by pulling a detachable cable connected to one end of a piston, thereby allowing inflation gas to flow from an attached pressure vessel into an inflatable raft includes a valve body having an inlet, an outlet, an internal cylinder open at one end to the valve outlet, and an inlet passage leading from the valve inlet to and intersecting with the midsection of the internal cylinder. A double-ended piston with O-ring seals on both ends is positioned in the internal cylinder so that one end blocks the passage to the outlet. In this position (valve closed) the O-ring seals are on opposite sides of the intersection of the inlet passage which results in a balancing of the gas pressure forces acting on the piston, thereby allowing the piston to be moved (for actuation) by simply overcoming the O-ring drag on the internal cylinder wall. This results in a low actuation force that is only remotely related to the operating pressure of the inflation system.

Abstract: A freeze protection valve can be reset under cold ambient conditions without the need for artificial heating of the valve's temperature sensor. An auxiliary latch is used to hold the valve element closed. The auxiliary latch is automatically released as the primary latching mechanism of the valve becomes operative upon an increase in temperature of the liquid system served by the valve. Release of the auxiliary latch is effected by virtue of a small downward movement of the valve stem resulting from a camming action inherent in the operation of the valve's primary latch.In one version of the valve, a simple, drop-away key temporarily holds the valve stem down until the primary latch becomes operative. In another version, the valve stem is reset remotely through a bowden wire, and the resetting mechanism automatically engages an auxiliary latch.
