Abstract:
The invention relates to a cooling-water circulation system in an internal combustion engine (1), in particular in a motor vehicle. Said system has a radiator (23), a pump (3) and a latent heat accumulator (7) and/or an auxiliary heating device (8) in the circulation system. The pump (3) circulating the cooling water is a canned motor pump with revolutions which can be regulated in accordance with the temperature readings of the latent heat accumulator (7) or of the auxiliary heater (8) and/or the internal combustion engine (1)
Abstract:
The invention relates to a latent heat storage system for use on the cooling-water circuit of a vehicle combustion engine, whereby a motor-driven rotary pump is secured either at the edge of the storage system housing or inside said housing.
Abstract:
Disclosed is a cooler for use on the cooling-water circuit of a vehicle combustion engine, whereby a latent heat storage system and/or a motor-driven pump is/are secured to said cooler and connected in the cooling-water circuit.
Abstract:
Disclosed is a heating system or an air-conditioning intended for use on the cooling-water circuit of a vehicle combustion engine, whereby a latent heat storage system and/or a motor-driven pump is/are secured to said heating system/air conditioning and connected in the cooling-water circuit.
Abstract:
The invention relates to a latent heat storage device for use on the cooling-water circuit of a vehicle combustion engine with an interior space containing a storage medium, which passes from a solid to a liquid phase and vice versa, resulting in a volume change, whereby a volume change-controlled/affected sensor, switch or valve is connected to the interior space, either at the edge thereof or inside, of said latent heat storage device.
Abstract:
The invention relates to an electric motor, especially a split-ring motor, for a centrifugal pump, with an outer casing surrounding the motor through which the cooling liquid flows, in which the motor compartment is closed off on the face away from the drive side by a metal cover, on the inner side of which there is a heat-sink for heat-generating electronic components, and the outer edge of which bears on the cooling outer casing.
Abstract:
The protective device described has at least one sensor (sensor H, temperature sensor R1) which delivers an electrical signal to a control circuit. The sensor is of particular use in determining the operational status of an electrical consumer, in particular a rotary-pump motor, a slotted-tube pump motor or a fan motor (pump motor M). In addition, the protective device has a mains-operated supply (N), a cut-out switch (1) operated by a bimetallic strip (18) and designed to interrupt the consumer circuit, and a temperature-dependent resistor (19) designed to activate the bimetallic strip (18). The bimetallic strip (18) is biased by a spring, in the direction in which it bends, to keep it in mechanical and electrical contact with the resistor (19), and is thus connected electrically in series with the resistor (19) in the control circuit.
Abstract:
The invention relates to a split pot centrifugal pump with an electric motor secured on the pump housing and a split pot flange (10) on the split pot (6), in which the split pot with its split pot flange (10) is releasably secured to form a seal on the pump housing and the split pot (6) supports the stator (12) of the motor, wherein the motor stator (12) is secured to the pump of the split pot flange (10) by means of a plug connector.
