Title: Intake valve device for coolant compressor
Inventor: MURAYAMA TOSHIHIRO
IPC: F04B49/22
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To make variable the cross sectional area of an intake passage and properly restrain capacity at a high-speed operation by applying the constitution that an energizing member to energize a movable valve toward the prescribed direction is formed to be capable of contracting so as to move the movable valve for the expansion of a flow passage area, when a coolant gas flowrate reaches the first preset value. SOLUTION: When a rotor 2 is rotated via a rotating shaft 7 on the operation of an engine, a fluid drawn via an intake chamber 11 is boosted and discharged from a delivery port 5a via a delivery chamber 10. In this case, when the flowrate of coolant gas flowing out from an evaporator exceeds the prescribed value, the movable valve 31 of an intake device 30 is pushed downward against the force of an energizing member 32 made of a coil spring. As a result the opening area of an intake passage 22 is kept maximum. and the coolant gas enters the intake chamber 11 via an intake port 6a. When the flowrate of the coolant gas further increases at a high-speed operation, the movable value 31 is pushed further downward. and the intake passage 22 and the opening 34 of the movable valve 31 is vertically dislocated from each other.  A flow passage area is thereby restricted and compressor capacity is restrained.

Abstract: PURPOSE:To realize a function related to a service class without holding data on the service classes for respective extensions by deciding the service classes of the respective extensions based on the setting situation of the ringing designation line wires of line wire incoming calls allocated to the respective extensions. CONSTITUTION:It is set in RAM 12 whether respective line wires are to be rung or not in accordance with respective extension numbers. A controller 10 refers to RAM 12, calculates the number of ringing line wires of the respective extensoins becoming objects, and decides the service class according to the size of the number. It is assumed that one extension is in the middle of an extension call and one extension calls the other one at that time, for example. The controller 10 compares the service class of an interruption request-side (one extension) with that of an interrupted-side (other extension). When the interruption request-side is a high-order, the telephone set of the interrupted-side is instructed to ring an interruption sound. Thus, the number of the ringing line wires of the respective extensions can be calculated by fixedly weighting them for the respective line wires.
