A novel method for breaking the viscosity of an aqueous phase thickened with preferably hydrophilic polymers in the exploration and production of mineral oil and / or natural gas is proposed. For this purpose, the breaking is carried out via the formation of a low-viscosity emulsion, with water as the continuous phase, this emulsion being formed by the addition of at least one surface-active component to a system which consists of the thickened drilling fluid and an oil phase which is crude oil present in the reservoir and / or oil introduced into the reservoir. Solubilizers between oil phase and water phase and in particular non-ionic surfactants, cationic surfactants and / or amphoteric surfactants are used as a preferred surface-active component. In addition to the surface-active component, it is possible to use further components, which are demulsifiers, non-emulsifiers, co-surfactants or surface tension modifiers. With the aid of this method, with the simultaneous presence of an oil phase, the aqueous phase can be displaced as a low-viscosity system and finally discharged at the surface, extremely effective cleaning of the well being associated therewith. With regard to the cost-efficiency and from an environmental point of view, the use of chemicals can be completely dispensed with.

A compressor has an economizer injection line communicating into the compressor compression chambers. An unloader valve selectively communicates the economizer injection line back to a point upstream of the evaporator. When the compressor is run in unloaded mode, partially compressed refrigerant is thus returned to a point upstream of the evaporator. In unloaded mode, this results in a higher refrigerant mass flow through the evaporator, as compared to prior art where the bypassed refrigerant was returned downstream of the evaporator. This increases system efficiency by more effectively returning oil which otherwise might be left in the evaporator back to the compressor. Also, the amount of refrigerant superheat entering the compressor in unloaded operation is reduced as compared to the prior art compressor systems, wherein the bypassed refrigerant is returned directly to the compressor suction line. Reduced refrigerant superheat increases system efficiency, improves motor performance and reduces compressor discharge temperature.

A thermal by-pass valve for a heat exchange circuit includes a housing forming a chamber and a by-pass valve port surrounded by a valve seat. The valve port is located between first and second sections of the chamber. First and second oil ports open into the first section. At least a third port opens into the second section. A thermally sensitive actuator is mounted in the first section and has a body and a piston located at one end. The body is movable in the chamber in response to extension of the piston. A valve member is operably mounted on the body and is movable by extension of the piston. A spacer projects from and is connected to the body and forms a passage through which the piston extends. The spacer acts to maintain the adjacent end of the actuator body at least the length of the passage away from an end of the chamber. The spacer can have a valve portion to close a further valve port.

The present invention increases cold temperature oil flow through the variable cam timing (VCT) phaser to reduce the amount of time it takes to replace this oil with warmer low viscosity oil and thereby improve performance. Furthermore the oil flow through the VCT phaser is reduced once the oil temperature reaches the minimum operating temperature for the VCT phaser to operate and the VCT phaser is commanded to move from the park position. Therefore, the VCT phaser is charged with hot engine oil and is commanded to move from the parked position. The VCT phaser reduces oil flow through the phaser at high oil temperatures and low oil viscosity while adding the benefit of increased oil flow through the phaser at low oil temperatures and high oil viscosity to facilitate getting warmer oil into the VCT phaser sooner for increased VCT performance.

A refrigerant system has at least one unloader valve selectively communicating refrigerant between the compressor compression chambers and a point upstream of the evaporator. When the compressor is run in unloaded mode, partially compressed refrigerant is returned to a point upstream of the evaporator. In an unloaded mode, a higher refrigerant mass flow rate passes through the evaporator, as compared to prior art where the by-passed refrigerant was returned downstream of the evaporator. This increases system efficiency by more effectively returning oil which otherwise might be left in the evaporator back to the compressor. Also, the amount of refrigerant superheat entering the compressor in unloaded operation is reduced as compared to the prior art compressor systems, wherein the by-passed refrigerant is returned directly to the compressor suction line. Reduced refrigerant superheat increases system efficiency, improves motor performance and reduces compressor discharge temperature. Also, by moving the unloader line further away from the compressor, the compressor replacement is simplified as there is no connecting unloader line directly in front of the compressor.
