摘要： A downshift control determines whether a commanded downshift is a downshift oriented toward minimum shock or a downshift oriented toward responsiveness, based on inputs from various sensors. The oil pressure on the hydraulic servo which controls the releasing-side friction engagement element is controlled based on the determined downshift type (DT), so that the releasing-side friction engagement element is released in accordance with a selected one of a plurality of release patterns, i.e., release patterns corresponding to different downshift type indexes (Dt). The releasing speed of the releasing-side friction engagement element is changed in accordance with the downshift type. By properly determining the type of downshift, it becomes possible to realize a shift of a type in accordance with the driver's intention.

摘要： A system for control of the discharge pressure of an input clutch hydraulic servo at the time of a D→N shift, in which the peak value (DN_Omega_max) rate of change of the rotational speed of an input shaft increases if the initial value (DN sol Sweep Start SLT signal) of the pressure adjusting control becomes high or low. A convergence region (DN_Omega_limit_max) is provided. On the basis of comparison between the previous peak value (DN_Omega_max_ave1) and the present peak value (DN_Omega_max_ave2), and the direction of correction, the learning is performed in accordance with various maps in a direction toward the convergence region.

摘要： A compressor capacity control operation mechanism includes a pilot valve (flow channel switching valve) having capillary tubes, a suction branching pipe, an intermediate pipe, and a discharge branching pipe. The suction branching pipe is connected to a first capillary tube and branches off from a compressor suction pipe. The intermediate pipe is connected to a second capillary tube and a compressor cylinder intermediate part. The discharge branching pipe is connected to a third capillary tube and branches off from a compressor discharge pipe. Preferably, the suction, intermediate and discharge branching pipes have larger diameters than the first second and third capillary tubes. Also, the pilot valve preferably has a flow channel configuration switchable between first and second states in which the first, second and third capillary tubes are connected differently in the first and second states.

摘要： An expansion valve for a refrigerant circuit of a refrigeration apparatus is configured to depressurize a liquid refrigerant. The expansion valve includes a valve main body with a valve seat opening into a valve chest formed in the valve main body and a valve body movable relative to the valve chest in a reciprocating manner. An orifice is formed in the valve seat. The orifice has an orifice entrance with a smallest diameter, an orifice middle section widening in diameter along a direction of refrigerant outflow from the orifice entrance so as to form a first taper angle, and an orifice exit either widening in diameter or not in diameter along the direction of refrigerant outflow from the orifice middle section so as to form a second taper angle smaller than the first taper angle.
