  • Patent number: 4664071
    Abstract: An adapter for converting a condenser into a thermal siphon radiator includes a housing that has an outlet port connected to the fill inlet of the condenser, a side inlet port connected to a conduit and a fill inlet that is sealingly engaged to a radiator cap. The radiator cap has a valve element that seats against a sealing surface in the adapter. The surface is interposed between the inlet and the two ports. In addition, an overflow and return port is positioned above the sealing surface and is connected to a reservoir.

  • Patent number: 4563987
    Abstract: An automatic engine control circuit and clutch actuating mechanism includes a primary timer which defines an off time and on time and a starting circuit that includes a second timer mechanism that determines the number of times the engine is cranked the duration in each starting crank. The engine control circuit also has a warm up timer that provides for an engine warm up period before a clutch actuating circuit is actuated to engage a clutch. The clutch actuating mechanism has a shaft with adjustable spring clips that flip limit switches in the clutch actuating circuit. A supplemental timer is operatively connected to the primary timer to allow for warm up periods without engagement of the clutch when the primary timer is in its off mode. Other safety sensors are operatively connected within the circuit to disable the engine if any unsatisfactory conditions are sensed by the circuit.

  • Patent number: 4344390
    Abstract: A piston-cylinder assembly of an internal combustion engine is provided which includes a cylinder liner mounted within a bore formed in an engine block, and a cylindrical spacer extending axially and endwise from the liner and coacting therewith to form a cylinder in which a piston is mounted for reciprocatory movement. An end piece overlies an end of the spacer and is supported by the latter. The end piece substantially closes off one end of the cylinder and the piston is in close proximity thereto when at one stroke limit. When the piston is at the one stroke limit, it coacts with the end piece and the spacer to define a combustion chamber. The end piece is secured in assembled relation with the spacer by a first means. A second means is provided for effecting substantial thermal insulating of the block, liner and first means from the heat of combustion which is generated in the combustion chamber during operation of the engine.

  • Patent number: 4328772
    Abstract: A combustion chamber for an internal combustion engine is provided having a cylindrical member, an end piece overlying one end of the member, and a piston mounted for reciprocatory movement within the member and when at a predetermined relative position, coacting with the end piece and member to form a combustion cavity. A compliant gas seal is positioned between the end piece and member and is in surface contact therewith. The seal encompasses the combustion cavity and has a portion thereof continuously exposed to the cavity.
