摘要： An expansion valve adapted to achieve a stable operation in case of variations of the pressure of a high-pressure refrigerant is actuated by a power element transmitting an opening force to a valve body via a rod located between said power element and said power body by applying couple forces to the rod and generating a retarding force for the rod while the rod is guided in the direction of its shaft line.

摘要： In a refrigerating cycle with a by-pass line 5 detouring the condenser 2 in an auxiliary heating mode the amount of circulated refrigerant is controlled in accordance with load, etc. so that the heating can be suited to such conditions. A regulator 20 for controlling the outlet pressure of the evaporator to a fixed level allows to use an evaporator 4 having ordinary pressure resistance. An accumulator 6 for temporarily storing low-pressure refrigerant liquid is provided between the outlet of evaporator 4 and a compressor 1. In an auxiliary heating mode the amount of the circulated refrigerant passing the by-pass line 5 is controlled by the accumulator 6. Simultaneously the regulator is controlling the outlet pressure of the evaporator to an essentially fixed level.

摘要： A differential pressure is added to an inhalation pressure on an arbitrary level by a solenoid actuated piston valve and by the inhalation pressure. The differential pressure is transmitted into a capacity variation mechanism (30) of the compressor (10) to change the compressor capacity. The capacity controller (20) is a fixed differential pressure valve controlling the differential pressure by the pressures at the ends of a piston valve (25). The solenoid of the valve is driven by a coil (21) to which current is supplied on demand.

摘要： A pilot operated flow regulating valve has pressure governing chamber receiving a moveable pressure receiving member for common movements together with a main valve member (4) of said pilot operated flow regulating valve in relation to a fixed valve seat (1) and by a differential pressure exerted to said pressure receiving member from both surface sides, further has a leak route (16) of small cross-section extending between said pressure governing chamber (8) and either the upstream or the downstream side of said valve seat (1), and has a constant differential pressure control valve for selectively either controlling the pressure inside said pressure governing chamber (8) or for blocking a pilot route extending between said upstream and downstream sides.

摘要： In a radiator assembly of a water cooled engine driven vehicle heating is performed by a compartment heat exchanger 8. As long as the temperature of the cooling water is low it does not suffice to sufficiently heat by compartment heat exchanger 8 shortly after engine start an auxiliary heating equipment is used. Said auxiliary heating equipment includes a heat exchanger 7 at the heating side, a heat exchanger 9 at the endothermic side and a Peltier element 10. Said Peltier element 10 leads to high energy efficiency because it provides a quantity of heat which is more than the quantity of energy charged into the Peltier element, since it transfers Joule heat generated by the charge energy to the heat exchanger 7 and further transfers a quantity of heat to heat exchanger 7 as absorbed in a heat exchanger 9 at the endothermic side from an endothermic surface of said Peltier element by a Peltier effect to the exothermic side.

摘要： In a four-way directional control valve (6) of simplified construction and reduced manufacturing costs first and second hollow cylindrical valve elements (20a,20b) are arranged coaxially. Adjacent to opposite ends of said valve elements (20a,20b) first and second valve seats (13,14) and first and second valve closure elements (15,17) are provided. First and second pressure-regulating chambers (41,42) are arranged between separator walls (37,38) of said valve elements (20a,20b) and first and second partition walls (35,36) associated to said first and second valve seats (13,14). A pilot valve (30) can be switched between switching positions for introducing high-pressure fluid originating from a first pipe into the first or second pressure-regulating chamber (41,42) via a common high-pressure passage (31), a high pressure introducing hole (32) and two pilot holes (33,34) respectively associated to said pressure-regulating chambers (41,42). Said control valve (6) can be switched into a state where the first pipe (A) communicates with the fourth (C) and the second pipe (B) communicates with the third pipe (D) and to another state where the first pipe (A) communicates with the third pipe (D) and the second pipe (B) communicates with the fourth pipe (C).
