There is disclosed herein an accumulator for an automotive air conditioning system. The accumulator includes a sump for collecting oil to be provided to the air conditioning compressor. There is also disclosed an outlet tube in the accumulator, the tube having a flange opening and a necked-down portion a predetermined distance from the flange opening.

Accumulator for vehicle air conditioning system

An apparatus for attenuating noise produced by fluid pressure pulsations in a hydraulic system in an automotive vehicle is disclosed. The apparatus includes a muffler device comprising a generally elongate tubular member having a predetermined number of attenuating zones therein, each zone having a cross-sectional area of different size than the cross-sectional area of the tubular member. The attenuating zones are spaced at unequal lengths from one another to achieve maximized noise reduction benefits.

Tuned tube muffler for an automotive vehicle

This specification relates to a heat exchanger (10) of the type wherein a plurality of elongated plates (12) are laminated together to define a plurality of passageways (14) for movement of a fluid therethrough. Each of the passageways (14) are formed by inwardly facing surfaces of a pair of laminated plates (12--12) which define a central fluid conducting section (34) located between reservoir sections (32--32) at each end thereof. Adjacent of the passageways (14--14) have heat transfer fins (18--18) located therebetween. Reservoir sections (32--32) of adjacent ones of the passageways (14--14) are interconnected so that a fluid may flow therethrough. The improvement of this invention is made to the laminated plates and it includes a plurality of beads formed on each of the pair of laminated plates (12--12). The beads formed on each of the plates are of two distinct varieties. A first variety of the beads (40-1) extends above a surface of each laminated plate (12) and terminates in a relatively flat upper surface. A second of the variety of beads (40-2) extends above a surface of each laminated plate (12) and terminates in a bowed upper surface. The first and the second variety of beads (respectively 40-1 and 40-2) are so constructed and arranged that the first variety of beads (40-1 on one of the elongated plates (12) are in bonding contact with the second variety of beads (40-2) on the other of the pair of laminated plates (12) and vice-versa.

Heat exchanger structure

A plate and fin heat exchanger in the form of a refrigerant evaporator. The heat exchanger comprises a plate and fin structure providing alternately channels for the flow of refrigerant and spaces for the flow of air. An apertured inlet manifold is in communication with the refrigerant flow channels. A refrigerant distribution tube is inserted into the inlet manifold through the aperture in the latter. The distribution tube is provided with a series of orifices formed in the tube wall in register with the refrigerant flow channels. The improvement comprises a construction and arrangement in which the orifices are directed toward the air inlet side of the heat exchanger. Preferably, the orifices are directed to the air inlet side of the heat exchanger at an acute angle to a horizontal plane, the angularity being on the order of 0.degree. to 15.degree. relative to the horizontal plane and below the latter.
