Publication number: 20060166569Abstract: An outboard drive for boats, having a steerable underwater housing (1) which has a wing-profiled portion (2). Projecting at an approximately 90 degree angle from the aft part of one side face (31) of the wing profile is a face portion (32), the lateral extent of which amounts to about 1-2% of its distance to the steering shaft (36) of the wing profile. As a result of this construction, a lifting force will be generated during forward travel in the water. The face portion is configured on that side of the profile which produces a lifting force counter-directional to a steering force, deriving from the motor torque, upon the wing profile.Type: ApplicationFiled: December 22, 2005Publication date: July 27, 2006Applicant: AB VOLVO PENTAInventors: Oddbjorn HALLENSTVEDT, Staffan MANSSON

Patent number: 7059167Abstract: Method and arrangement for accommodating indirect ascertainment of fill-characteristics of fluid tanks on marine vessels. The invention includes providing an experientially-based mapping of volume characteristics of a fluid tank positioned on a marine vessel that are correlated with respect to measurable fluid surface positions within the fluid tank. In consideration of this volume characteristic mapping, fluid fill condition information is output for operator use based on quantification of a parameter other than sensed fluid level in the fluid tank. While it is contemplated that the other parameter may be any characteristic that readily reads back to the volume characteristic mapping, it is particularly advantageous, and a preferred embodiment of the invention, that the other parameter be a volumetric quantification of fluid consumed out of the tank that can be compared to an earlier ascertained tank volume.Type: GrantFiled: January 31, 2003Date of Patent: June 13, 2006Assignee: AB Volvo PentaInventor: Per Nestvall

Publication number: 20060112677Abstract: Method and arrangement for providing a compressed air system in a vehicle that includes a connection (6, 10) for delivering compressed air from a compressor (2) to the rest of the compressed air system (1). An oxidation catalytic converter (9) is included that is designed to clean the compressed air and which is located along the connection (6, 10). The connection (6, 10) includes a line (10) that forms a connection between the oxidation catalytic converter (9) and the rest of the compressed air system. The invention also includes a valve (11) that is arranged upstream of the rest of the compressed air system (1) and that can be adjusted so that in a first position it will allow and in a second position will prevent the delivery of air to the rest of the compressed air system (1), depending on the operating condition of the compressor (2). The invention provides an improved system in which the risk of contaminated air being delivered to the compressed air system is minimized.Type: ApplicationFiled: August 3, 2005Publication date: June 1, 2006Applicant: AB VOLVOInventor: Mats SABELSTROM
