Abstract: PURPOSE:To enhance an oil separating efficiency by rotating vapor phase refrigerant and oil introduced from an inlet tube into a vessel body at a high speed to generate a swirling down flow, separating oil by a centrifugal force, and interposing a deflector between an oil separator and an oil reservoir. CONSTITUTION:An outlet 3 directed vertically and an inlet tube 4 directed substantially in a tangential direction are provided at upper parts of a vessel body 2. Vapor phase refrigerant and oil introduced into the body 2 through the tube 4 are rotated at a high speed to generate a swirling down flow S, oil O is separated by a centrifugal force in a conical member 5 and adhered to an inner wall surface 5a. The adhered oil is dropped along the surface 5a to be stored in an oil reservoir 6 of a lower part of the body 2, and returned through an oil return tube 7. In this case, oil which is not separated is adhered to a deflector member 8 interposed between the member 5 and the oil reservoir 6 as an oil separator to be separated by the member 8, thereby enhancing oil separating efficiency.

Filed: 1992-06-09
Abstract: PURPOSE:To easily prepare documents regardless of relation between the constitutive elements of documents or between documents by referring to the relation between defined constitutive elements, deciding the contents of the other related constitutive element when the contents of a certain constitutive element are decided, and preparing the document. CONSTITUTION:In the case of preparing documents, an input from a user is received by an input means 1, the inputted constitutive element is judged by a structure analyzing means 4, and the document is prepared by a document preparing means 6. At such a time, the document preparing means 6 requires the investigation of the presence/absence of the relation to an information retrieving means 5. While referring to the relation preserved in a preserving means 9, the information retrieving means 5 investigates whether there is any constitutive element related to the inputted constitutive element or not. When there is the related constitutive element, processing is performed according to the defined relation by a relation processing means 8 while referring to a processing method preserved in the preserving means 9. Thus, the contents of the other related constitutive element are automatically decided.

Abstract: PROBLEM TO BE SOLVED: To provide a pressure control device capable of preventing a filter from breakage and removing foreign matter of minute size. SOLUTION: A pressure control valve 20 is installed on a delivery pipe, and a housing 21 of the valve 20 accommodates a filter 30, valve seat member 22, ball 40, spring 41, etc. When the pressure of the fuel accumulated in a pressure chamber of the delivery pipe exceeds a specified level, the ball 40 separates from the seat 26 against the energizing force of the spring 41.
