Abstract: The light source device 10A has a light-emitting tube (11) (radial light source) and a reflector (12A). A cylindrical heat-conductive member (14A) is attached on an outer surface of a first sealing portion (114A) near a neck portion (121A) of a reflector (12A) in sealing portions (114) of the light-emitting tube (11). The heat-conductive member (14A) is attached along the outer surface of the first sealing portion (114A) with an end thereof being extended to a section near a light-emitting portion (113). A heat-radiation fin (15A) is attached on the other end of the heat-conductive member (14A).

Abstract: A light source that prevents broken pieces from dispersing to the outside without increasing the number of components while efficiently cooling a light-emitting tube is provided.

Abstract: A light source lamp unit (10) includes a light source lamp (11), an ellipsoidal reflector (12) and a plate body (19). The plate body (19) is provided behind the reflector (12) with a gap kept therebetween, which has a shape corresponding to the profile of a reflecting portion (122) of the reflector (12). A cooling channel for passing a cooling air is formed between the plate body (19) and the reflector (12). The width of the cooling channel in a direction along an optical axis of the light source lamp (11) is minimized at a part near a neck portion (121) of the reflecting portion (122) and enlarged toward the peripheral edge of the reflecting portion (122) of the reflector (12).

Abstract: A pressure differential valve connected to a refrigerating circuit piping which, when a refrigerating cycle stops, blocks the high pressure coolant from diffusing into the low pressure section. Said pressure differential valve comprises a valve body having a first inlet, a first outlet, a second inlet and a second outlet; a valve disk installed in a valve chamber between the first inlet and the first outlet to open or close the passage between the first inlet and outlet, the valve disk being urged to open by a spring; a diaphragm installed between the second inlet and the second outlet to form pressure chambers; and a check valve secured to the diaphragm and communicating to both of the pressure chambers; whereby when the check valve is closed, the diaphragm causes, through a connecting rod, the valve disk to close. Said valve disk has radially projecting guide vanes attached to the axially extending portion of the seat-contacting disk to form spaces through which coolant can flow.
