摘要： A variable displacement pump including a chamber volume varying mechanism including a moveable member, a first biasing member always biasing the moveable member in such a direction as to increase volumes of the working fluid chambers, and a second biasing member that is disposed with a set load and applies a biasing force to the moveable member in such a direction as to increase the volumes of the working fluid chambers when the moveable member is displaced against a biasing force of the first biasing member by a predetermined amount or more. The biasing force of the first biasing member is set such that before the moveable member is displaced against the biasing force of the first biasing member, the valve timing control device is shifted to a release state in which an open-and-closure timing of an engine valve is variably controlled.

摘要： This invention relates to a method of producing a high-melting powder of 2,2-bis�4'-(2",3"-dibromopropoxy)-3',5'-dibromophenyl!propane characterized by comprising a step of adding water to a solution of 2,2-bis�4'-(2",3"-dibromopropoxy)-3',5'-dibromophenyl!-propane in an organic solvent in the presence of a surfactant to give a water-in-oil emulsion and a step of removing the organic solvent from the emulsion in the presence of a crystal nucleus to induce crystallization to give an aqueous dispersion of 2,2-bis�4'-(2",3"-dibromopropoxy)-3',5'-dibromophenyl!propane. In accordance with this invention, crystallization is carried out in the state of an emulsion under assistance of a surfactant so that an ordinary stirrer can be used in production without resort to any special high-shear stirring equipment. Moreover, since a high-melting grade of 2,2-bis�4'-(2",3"-dibromopropoxy)-3',5'-dibromophenyl!propane is obtained as an aqueous dispersion, workability and safety in the subsequent processing are improved.
