IPC: F02M61/20
Filed: 1989-10-16
Abstract: PURPOSE: To reduce injection rate during light load operation and reduce noise, hydrocarbon and nitrogen oxide emissions by effectively limiting opening of a poppet valve during light load engine operation by means of an actuating piston. CONSTITUTION: Fuel injection pressure acts on an upper surface 53 of an actuating piston 46, force is transferred to a stem 30 and a poppet valve 22 is moved countering a spring 34. Fuel flows to upper and lower orifices 58, 60 through passages 42, 54, 56.

During light load operation, only the lower orifice 58 is used and fuel injection rate is reduced so that noise, hydrocarbon and nitrogen oxide emissions can be reduced.  During heavy load operation, the poppet valve 22 is moved in response to a high injection pressure until a shoulder 64 collides with a stop member 38 to expose the orifices 58, 60 below the lower end portion 28 for delivering the fuel necessary for operation.

Title: Multi-room type air conditioner
Inventor: KITAYAMA HIROSHI
IPC: F25B13/00
Filed: 1989-10-13
Abstract: PURPOSE:To operate the title air conditioner while maintaining optimum operational pressure conditions by constituting a refrigerant circulating path in the form of a ring, which connects an outdoor unit to a plurality of indoor units, and connecting a liquid tube between an outdoor expansion valve and indoor expansion valves to a tube between a four-way valve and an outdoor heat exchanger by a bypass provided with an electrically operated expansion valve. CONSTITUTION:In a case where the performance of indoor units becomes extremely small and a 1-HP operation is carried out, indoor side expansion valves 8a, 8b, 8c are closed while an indoor side expansion valve 8d is opened, and the performance of compressor 2 shows a 2-HP operation in a lower limit. In this case, the pressure of condensation (or an equivalent temperature) is detected, and when it is lower than a preset value, an electrically operated expansion valve 15 is opened. Thereby, gas discharged from the compressor 2 is made to flow to two circulating paths i.e., a path to an outdoor side heat exchanger 4 and a bypass 16. At the same time, the flow rate of refrigerant passing through the outdoor side heat exchanger 4 and the bypass 16 is regulated by regulating the opening degree of the electrically operated expansion valve 15, and the pressure of condensation is made to approach the preset value while controlling the performance of condensation. This method makes it possible to carry out a cooling operation while always maintaining optimum operational pressure conditions throughout the year irrespective of the number of indoor units.
