Title: Hydraulic rotation actuator
Inventor: SOENDERGAARD JOERGEN
IPC: F16K31/163
Filed: 1985-04-16
Abstract: The actuator includes an actuation piston (9) in a housing (4), which via a toothed bar (10) engages with an exterior tooth system on a cross-mounted actuator spindle (12). The actuator piston's (9) advance and with it the actuator spindle's (12) rotation is controlled with the help of a hydraulic control pressure led to a working space (6), while the actuator piston's (9) return takes place with the help of a gas pressure spring, which is compressed at the same rate as the advance of the actuator piston.In one version the actuator piston (9) is hollow and embodies the compression chamber (16) with an enclosed pressurized gas volume and the further compression necessary for the return of the actuator piston (9) is brought about with the help of a reaction piston (14) positioned at the end of the actuator piston's (9) end turned facing the opposite working space (6), which during the advance of the actuator piston in shifted into the compression chamber (16) herein. The reaction piston has a shoulder (18) which in the reaction piston's (14) mounted condition prohibits this from being shifted completely out of the actuator piston (9).In such a way an especially compact actuator is produced, which furthermore is easy to service, in that elimination of any irregularities concerning the compression chamber can take place during removal of the whole actuator.<IMAGE>

Abstract: A backshelf compensating exhaust hood includes an upper wall passageway for forming and redirecting an induction air stream into and through an exhaust chamber to an exhaust passageway, the upper wall passageway extends through the upper wall to a smooth curved reverse passageway redirects the air into a short slot which discharges a stream into the upper end of the exhaust chamber. A forward tilted filter is located in the exhaust chamber to form the back wall of the exhaust chamber and with the lower end spaced inwardly of the upper end and with the upper portion aligned with the induction air stream. The filter is oriented to define an essentially right angle with the interior upper wall of the exhaust chamber. The top wall of the exhaust chamber extends inwardly and upwardly slightly to the filter. The induction air supply passageway is a relatively large passageway which has a depth which is a multiple of the depth of the slot. The inlet expands slightly to the deflector and reverse passageway to the discharge slot. The discharge slot includes a short extension of the deflector wall as an essentially flat wall which extends parallel to the top wall of the exhaust chamber. For a gas fired unit, an exhaust duct is located to the backside of the hood for upwardly spaced alignment with flue duct of the equipment. The spaced exhaust duct of the hood projects upwardly into the exhaust passageway for exhausting of the combustion gases and the secondary air introduced between the flue duct and the exhaust duct.
