Abstract: The invention concerns a regulator thermostat support of heat engine with external hot water circuit, consisting of a specific regulator thermostat housing support (11) replacing the existing support and comprising means (12, 13) for mounting a double branch pipe connecting said support to a liquefied gas vaporization system or to another calorie consuming equipment. Said branch pipe constitutes a bypass for the engine coolant and the regulator thermostat support being designated so that the flow rate in said branch tube is controlled by the regulator thermostat. It serves to ensure preheating of liquefied gas (LPG), or other fuel, used in a particular for marine engines of all types, tow- or four-stroke, carburetor or injection, outboard or inboard, but which can also be used for land engines or for other applications.

Abstract: Arrangement for expanding liquefied gas. The arrangement includes a vaporizing element having a heat exchanger. The heat exchanger has an impermeable enclosure containing a heating fluid and a vaporizing tube made of a heat conducting material through which the liquefied gas passes. The vaporizing tube includes an intake connected to a supply reservoir and an outlet supplying vaporized gas. An element is provided for regulating a flow rate and a pressure of vaporized gas. A tube connects the outlet of the vaporizing tube to the element for regulating a flow rate and a pressure of vaporized gas. The element for regulating a flow rate and a pressure of vaporized gas is connected to an engine. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.

Abstract: Thermostat or calorstat support device for a heat engine having an external hot water circuit. The support device includes a support housing and a connecting arrangement connecting the support housing to a calorie consuming arrangement. The support housing is arranged to allow a controlled flow through the connecting arrangement.

Abstract: A system for vaporizing and supplying liquefied petrol gas to an internal combustion engine, the internal combustion engine comprising an oil circuit for lubricating the engine and utilizing one of a carburetor and fuel injection. The system includes a vaporizing housing having a temperature chamber and of a vaporizing chamber. The temperature chamber is connected to the oil circuit for lubricating the engine. The vaporizing chamber is connected to a liquefied gas tank and to one of the carburetor and the fuel injection, the liquefied petrol gas being heated by the engine oil.

Abstract: A liquefied gas evaporating device supplies liquefied petroleum gas to a marine engine, wherein the device includes a box that includes a heating body incorporating an evaporating chamber and a thermal chamber which are contiguous and separated by a common wall. The thermal chamber hot sea water coming out of a cooling circuit of an engine to flow therethrough via an accelerating pump mounted on an evacuation pipe of the cooling circuit. The heating body is made of a material that resists corrosive action of sea water.
