Title
(EN) POWER-OPERATED DEVICE WITH A COOLING FACILITY
(FR) DISPOSITIF ACTIONNE PAR MOTEUR AVEC AGENCEMENT DE REFROIDISSEMENT
Abstract
(EN)
A cordless power-operated device, such as a saw (20), is powered by a low level D.C. voltage provided by battery pack cells to operate the saw in a cordless mode. The cells are housed in a container (32) which fits into a cavity (23) formed in a housing (22) of saw (20). Another container (66) includes a first section (64) which is shaped externally in the same configuration as container (32). First section (64) houses a voltage converter (62) which converts conventional A.C. voltage, such as 120 volts at 60 Hz, to the low level D.C. voltage required to operate saw (20). Container (66) can be inserted into cavity (23) of saw (20) and voltage converter (62) can be connected to a conventional A.C. source to operate the saw in a corded mode. Container (66) also includes a second section (68) which houses a cooling motor (70). Cooling motor (70) provides powered cooling of saw motor (28), the cooling motor and voltage converter (62).
(FR)
Un dispositif actionné par moteur non raccordé au réseau, tel qu'une scie (20), est alimenté en énergie par une faible tension de C.C. fournie par les cellules d'un bloc d'alimentation qui actionnent la scie lorsqu'il n'est pas raccordé au réseau. Les cellules sont logées dans un boîtier (32) qui rentre dans une cavité (23) du logement (22) de la scie (20). Un autre boîtier (66) comprend une première section (64) dont la forme extérieure correspond au boîtier (32). La première section (64) contient un transformateur de tension (62) qui transforme une tension de C.A. conventionnelle, telle qu'une tension de 120 volts à 60 Hz, en une faible tension de C.C., requise pour actionner la scie (20). Le boîtier (66) peut être inséré dans la cavité (23) de la scie (20) et le transformateur de tension (62) peut être connecté à une source conventionnelle de C.A. afin d'actionner la scie lorsqu'elle est raccordée au réseau. Le boîtier (66) comprend également une seconde section (68) qui contient un moteur de refoidissement (70). Le moteur de refroidissement (70) se refroidit lui-même le moteur (28) de la scie et le transformateur de tension (62).
