摘要： The two-cycle internal combustion engine includes an engine block having a cylindrical wall defining a cylinder having a head end, a piston mounted for reciprocative movement in the cylinder, and a passage in the engine block, such as an exhaust passage, a transfer passage, or a crankcase fuel intake passage, terminating at the cylinder wall in a port, such as an exhaust port, a transfer port or a piston-controlled, crankcase fuel intake port, having upper and lower edges. A valve mounted in the passage for movement relative to the port is operable to selectively vary the effective distance of one of the port edges from the cylinder head end and thereby provide the capability of varying the timing of the port opening and/or closing as required to obtain optimum engine performance at different operating conditions.

摘要： Disclosed herein is a pressure valve for use in any one of several cooling systems for different internal combustion engines also disclosed herein. The pressure valve is connected in series with a source of coolant and an engine coolant jacket for affording coolant flow from the source through the coolant jacket when the pressure in the coolant is above a first value and for affording continued coolant flow through the coolant jacket until the pressure in the coolant falls below a second value lower than the first value. The pressure valve comprises wall means defining a chamber having an inlet and an outlet including a valve seat, together with a valve member having a first surface movable relative to a closed position wherein the first surface sealingly engages the valve seat, which valve member also has a second surface facing away from the first surface. Means biasing the valve member toward the closed position are provided, together with a diaphragm having a portion connected to the valve member for proportionately related movement in common with the valve member, the diaphragm having a side surface positioned in spaced relation with respect to the second surface of the valve member so that liquid entering the inlet at a pressure above the first value is effective to displace the valve member from the closed position and so that the valve member remains displaced from the closed position until the pressure in the liquid entering the inlet falls below the second value.

摘要： A liquid flow metering system is disclosed which includes a pump disposed between a liquid supply and a reservoir. The reservoir includes an inlet connected to the pump, an air/liquid outlet and a liquid outlet. The air/liquid outlet is connected to an air separation chamber. The liquid outlet is connected to a flow meter and a liquid outlet valve. The air separation chamber is connected to an air outlet. The air outlet is connected to an air release valve. The air separation chamber accommodates an optical sensor for sensing the presence of air in front thereof and within the air separation chamber. The optical sensor, air release valve and liquid outlet valve are all linked to a controller. When the optical sensor senses air in front of the optical sensor, the sensor sends a signal to the controller to open the air release valve and close the liquid outlet valve. Conversely, when the optical sensor senses liquid in front of the optical sensor, the optical sensor sends a signal to the controller to close the air release valve and open the liquid outlet valve.
