Abstract: A piston for use in a compressor that compresses gas containing lubricating oil is disclosed. The compressor includes a housing having a crank chamber and cylinder bores for accommodating the pistons. A swash plate is located in the crank chamber and is supported on a drive shaft. The swash plate is operably connected to the pistons by shoes to convert the rotation of the drive shaft to reciprocation of each piston. Each piston has a head for compressing the gas supplied to the cylinder bore and a skirt projecting from the head toward the crank chamber and connected to the swash plate. A restrictor provided on the skirt slidably contacts an inner surface of the housing to prevent the piston from rotating in the cylinder bore. A sloped surface extends along the edge of an end face of the restrictor. The sloped surface guides the oil in the crank chamber toward the shoes when the piston moves from a top dead center position to a bottom dead center position.

Abstract: An improved viscous fluid type heater is disclosed. The heater has a heating chamber that has a inner peripheral surface and a pair of inner side surfaces and a heat exchange chamber disposed adjacent to the heating chamber. The heating chamber houses a cylindrical rotor that has an outer peripheral surface and a pair of outer side surfaces. The outer peripheral surface is opposed to the inner peripheral surface by a first space. The outer side surface is opposed to an associated inner side surface by a second space that communicates the first space. The rotor rotates and shears viscous fluid to generate heat in the spaces. The heat generated in the spaces is transmitted to the heat exchange chamber to heat circulating fluid circulating in the heat exchange chamber and an external fluid circuit. The rotor has a storing chamber defined therein. A first passage connects the first space with the storing chamber to shift the viscous fluid from the storing chamber to the first space.

Abstract: A swash plate is arranged to tilt between a maximum inclining angle and a minimum inclining angle based on differential pressure between a crank chamber and a suction chamber. At least one single-headed piston, that is coupled to the swash plate, is disposed in an associated cylinder bore and reciprocates at a stroke according to the inclining angle of the swash plate to compress refrigerant gas introduced to the cylinder bore from an external refrigerant circuit via the suction chamber. A pressure supply passage connects a discharge chamber with the crank chamber to supply the refrigerant gas from the discharge chamber into the crank chamber so as to increase the pressure in the crank chamber and a flow passage which allows flow of the refrigerant gas from the crank chamber to the suction chamber. An introducing passage introduces the refrigerant gas with low temperature from the external refrigerant circuit to substantially equalize the pressures in the crank chamber and the suction chamber.

Abstract: A combined evaporator and condenser for desalination of seawater which can be used on a ship for fresh water production, has plate type falling film heat exchange elements within a housing wherein a liquid heating medium such as hot engine jacket water circulates within lower internal spaces of the heat exchange elements for boiling seawater falling as a film down external surfaces of the elements and vapor boiled off from the seawater is conducted to upper internal spaces within the heat exchange elements for condensation therein to produce a stream of fresh water. The seawater film flows down the entire length of the external surfaces of the plate heat exchange elements, which have a transverse internal partition separating their lower and upper internal spaces and vertical partitions within the lower internal spaces for lengthening the flow path of the liquid heat exchange medium therethrough.

The valve plate is provided with a rib-formed support for supporting the suction valve when it is closed against the inlet port opening.

Abstract: A housing has a crank chamber and a plurality of cylinder bores. The housing also has a discharge chamber and a suction chamber, which are communicatable with the cylinder bores. A drive shaft is supported in the housing, and pistons are accommodated in the respective cylinder bores. A swash plate is supported on the drive shaft in such a manner that its inclined angle can be altered, so that the undulation of the swash plate causes the pistons to reciprocate. When this compressor is running with the swash plate set upright, a controller activates an electromagnetic solenoid to supply a lubricating oil to a pressure chamber from an oil-supplying pump. This causes the spool to shift to temporarily hold the swash plate to an inclined position from the upright position.
