摘要:
A reciprocating compressor, comprising a cylinder block (1) having a cylinder bore (12) formed therein, a rear head (3) fixed to the cylinder block through a valve plate (2) and having a suction chamber (26) and a discharge chamber (27) formed therein, a front head (4) fixed to the cylinder block (1) and having a crankcase (6) formed therein, pistons (13) reciprocatingly sliding in the cylinder bore according to the rotation of a shaft (7) installed so as to pass through the crankcase (6), a means for separating lubricating oil mixed in working fluid discharged into the discharge chamber (27), and an oil tank (30) for storing the lubricating oil separated by the oil separation means, wherein the lubricating oil stored in the oil tank (30) is cooled by working fluid sucked from the outside and led into the suction chamber (26), whereby the durability of sliding portions can be increased by effectively cooling the lubricating oil in the compressor to assure excellent lubrication at the sliding portions.
摘要:
An electromagnetic clutch capable of reducing attracting noise generated when an armature plate is attracted to the friction surface of a rotor, wherein the thickness of the projected part (32) of an elastic member (31) in the state of being compressingly held by an inner plate (26) and the armature plate (12) is increased more than the thickness of the projected part (33) of the elastic member (31) in the state of being compressively held by an outer plate (17) and the armature plate (12), whereby the volume of the projected part (32) of the elastic member (31) can be increased relative to that of the projected part (33).
摘要:
A serpentine type heat exchanger, comprising at least an inlet side header pipe, an outlet side header pipe, at least one serpentine tube which is extended from the inlet side header pipe, folded back in multiple stages with specified intervals, and led to the outlet side header pipe, and a corrugated fins disposed between multiple-stage folded-back refrigerant passages formed of the serpentine tubes, wherein the width of the heat exchanger in the direction of air flowing through the corrugated fins is formed within the range of approx. 35 mm or longer to 65 mm or shorter, the fin height of the corrugated fins is formed within the range of approx. 5 mm or longer to 13 mm or shorter, and the intervals between the folded-back refrigerant passages of the serpentine tubes are formed corresponding to the fin height.

A hole (TH) accommodating a steering member (S) extending in the lateral direction of a car is formed in the case (21) of a car air conditioner, the hole (TH) passing through the case (21) in thelateral direction of the car.
摘要:
A reciprocating refrigerant compressor, comprising a cylinder block having a cylinder bore (6), a compression chamber formed in the cylinder bore (6), a cylinder head allowing an intake chamber for storing refrigerant gas sucked into the compression chamber to be formed therein and connected to the cylinder block, a valve plate (2) disposed between the compression chamber and a low pressure chamber and allowing an intake port (60) for leading the refrigerant in the intake chamber to the compression chamber to be formed therein, and an intake valve (70) opening and closing the intake port (60), wherein the shape of the tip part of the intake valve (70) is formed to correspond to the shape of the intake port (60), the intake port (60) is formed in a noncircular shape, a part of the opening edge of the intake port (60) is projected to the inside of the intake port (60), and tangential lines (m) drawn from the projected parts (90, 91, 92, 93) are crossed with the opening edge of the intake port (60) at at least two positions.
摘要:
A safety device for vehicles, arranged in the vicinity of an air conditioner mounted on a vehicle, and having a function of discharging to the outside the leaking carbon dioxide when leakage of carbon dioxide is detected. When leakage of carbon dioxide is detected by a carbon dioxide leakage detecting means, a drive means actuates a ventilating means arranged in a duct providing communication between a bottom portion in a compartment and an outside of the compartment, so that carbon dioxide stagnating on the bottom portion in the compartment can be exhausted outside the compartment.
摘要:
A heat exchanger (1) formed by laminating tubes (2) and fins (3) alternately, and insert-connecting end portions of the tubes to header pipes (4), wherein the tubes (2) are formed by roll forming or press forming plate type tube materials, each of which comprises a core member of Al-Mn aluminum alloy, and a layer constituting an outer surface of the tube (2) and clad with a non-Si-containing Al-Zn aluminum alloy, whereby the corrosion resistance of the tube is improved.
摘要:
A heat exchanger capable of reducing the size of a header pipe, having a sufficiently high strength with respect to a pressure and provided with caps of a structure in which imperfect cleaning does not occur during a cleaning step, wherein the caps which seal both end portions of a cylindrical section constituting the header pipe are provided with annular grooves in which circumferential edges of the end portions of the cylindrical section are engaged along the whole circumferences thereof, whereby the cylindrical section is fitted in inner portions of the caps, this enabling an axial size of the header pipe to be reduced, the pressure resistance of the caps being improved by forming large-thickness parts on the sealed portions of the caps, outer flat portions of the caps being provided with projecting parts.
