Sheave surfaces 11a to 14a of a primary pulley 2 and a secondary pulley 3 contacting a V-belt 4 which is looped around the pulleys 2, 3 are provided with an initial wear height at which a reaction film between the V-belt 4 and the sheave surfaces 11a to 14a does not become worn and a sufficient oil keeping depth to promote generation of the reaction film such that metallic contact does not occur between the sheave surfaces 11a to 14a and the V-belt 4.
摘要:
A hydraulic control apparatus includes a continuously-variable transmission; a line-pressure control section configured to produce a line pressure by adjusting a discharge pressure of an oil pump; a first hydraulic-pressure control section configured to adjust a first hydraulic pressure based on the line pressure, the first hydraulic pressure being supplied to the drive pulleys; and a second hydraulic-pressure control section configured to adjust a second hydraulic pressure based on the line pressure, the second hydraulic pressure being supplied to the driven pulleys. The continuously-variable transmission includes a pair of drive pulleys including a first movable pulley and a first fixed pulley; a pair of driven pulleys including a second movable pulley and a second fixed pulley; and a belt wound between the pair of drive pulleys and the pair of driven pulleys. The line-pressure control section is configured to adjust the line pressure to a value set by adding a margin pressure to higher one of the first hydraulic pressure and the second hydraulic-pressure, and configured to reduce the margin pressure when the first hydraulic pressure is higher than the second hydraulic pressure.

摘要:
An adsorption heat pump is provided in which water vapor can be efficiently adsorbed and desorbed using a heat source having a lower temperature than ones heretofore in use because the pump employs an adsorbent which has a large difference in water adsorption amount in adsorption/desorption and can be regenerated (release the adsorbate) at a low temperature.The invention provides an adsorption heat pump which comprises an adsorbate, an adsorption/desorption part having an adsorbent for adsorbate adsorption/desorption, a vaporization part for adsorbate vaporization which has been connected to the adsorption/desorption part, and a condensation part for adsorbate condensation which has been connected to the adsorption/desorption part, wherein the adsorbent, when examined at 25° C., gives a water vapor adsorption isotherm which, in the relative vapor pressure range of from 0.05 to 0.30, has a relative vapor pressure region in which a change in relative vapor pressure of 0.15 results in a change in water adsorption amount of 0.18 g/g or larger.

摘要:
The present invention provides an adsorbent for adsorption heat pump and humidity-control air conditioner, which is capable of adsorbing an adsorbate therein and desorbing the adsorbate therefrom in a narrow relative vapor pressure range, and can be regenerated (desorption) at a low temperature. Also, the present invention provides an adsorption heat pump and humidity-control air conditioner using the adsorbent which can be effectively operated even by a low-temperature heat source, as well as methods of operating the adsorption heat pump and humidity-control air conditioner by effectively utilizing low-temperature exhaust heat. The absorbent of the present invention comprises zeolite containing (i) aluminum, (ii) phosphorus and (iii) iron and/or gallium in a skeletal structure thereof, which is substantially free from change in structure upon subjecting the adsorbent to adsorption and desorption of water vapor.

Subjects for the invention are to provide a zeolite reduced in performance deterioration in repetitions of use or during long-term use and a process for producing the same and to provide an adsorbent comprising the zeolite and a heat utilization system or the like employing the adsorbent. The invention relates to a zeolite which has a framework density of from 10 T/nm3 to 16 T/nm3 and a carbon content of from 1% by weight to 6% by weight and satisfies the following (1) or (2): (1) the zeolite is an aluminophosphate which has a nitrogen content of from 0.5% by weight to 12% by weight and in which the aluminum may be partly replaced by Me; (2) the zeolite is a silicoaluminophosphate in which the aluminum may be partly replaced by Me and which, when burned to a carbon content lower than 0.3% by weight, retains the framework structure possessed by the silicoaluminophosphate before the burning: (provided that Me in (1) and (2) above is at least one element selected from the elements in Groups 2A, 7A, 8, 1B, and 2B of the periodic table).
