An automatically actuated, pressure responsive air intake valve for an internal combustion engine generally a fixed valve seat housing and a sliding valve member. The valve seat housing is threaded into the head of a working chamber on an internal combustion engine. The sliding valve member reciprocates through the housing in response to differential pressures on either side of the valve. The sliding member has a hollow chamber that opens in a sidewall of the valve seat housing, thereby directing a stream of air outward from the valve structure. By providing multiple valves in the head of the cylinder, a swirling effect may be accomplished to better distribute the fuel/air mixture and enhance cooling of the cylinder.

A dip jibe spinnaker pole constituted by an elongated spinnaker pole tubular body having an inboard end fitting at one end for detachably pivotably mounting the spinnaker pole to the mast and provided with an outboard end fitting about which four sheaves are pivotably mounted via bases to the periphery of the outboard end fitting stinger rod for articulation through an arc of at least 180. degree. at four circumferentially spaced positions. Three snatch guys led through the pole from the inboard end and through the outboard end fitting and through respective sheaves terminate in snap shackles for loosely coupling of the same to sheet/guy control lines connected at one end respectively to port and starboard clews at the foot of the spinnaker sail. A baby lift line is led through the pole from the inboard end and through the outboard end fitting and through the fourth sheave at the top of the pole outboard end fitting, with the snatch guys and the baby lift being controlled at the inboard end of the spinnaker pole to eliminate the need for a bow man and to permit one man on one side of the spinnaker pole to control all of the lines necessary to effect a dip pole jibe of the spinnaker.

An internal combustion engine having two parallel cylinders, namely, an induction cylinder and a power cylinder, whereby the power, ventilation (comprising simultaneous intake and exhaust), and compression events within the power cylinder completely define the cycle of the engine, with induction in the induction cylinder being an auxiliary and incidental function to the cycle within the power cylinder, such that engine cooling and fuel efficiency are improved over prior art internal combustion engines. Interconnecting the power cylinder and the induction cylinder is a transfer chamber which opens into the top of the power cylinder, which chamber in turn is equipped with a one way, pressure responsive transfer valve for allowing air to flow into the power cylinder when pressure therein falls below the pressure in the induction cylinder. An exhaust port is likewise positioned near the bottom of the power cylinder. With the exhaust port thus positioned just above the bottom of the stroke of the power cylinder, and with the inlet valve located at the opposite end of the cylinder, fresh air flows in the axial direction of the cylinder towards the exhaust port, cooling the surfaces of the cylinder and the piston as it flows.
