Patent number: 8668044Abstract: There is provided a circulation line (39) for circulating pressurized oil from an accumulator (11) into a housing (15) of a steering valve (14). An orifice joint (41) is provided along the path of the circulation line (39). The orifice joint (41) is removably mounted on the housing (15) of the steering valve (14) from outside. An orifice portion (42) of the orifice joint (41) applies a throttling function to the circulating oil liquid whereby a frictional heat is generated therein. The oil liquid in a warm state flows through a communication passage (21), passages in a spool valve (16), and a low pressure side passage (18B), thus enabling the steering valve (14) to be always in a warm state.Type: GrantFiled: July 1, 2010Date of Patent: March 11, 2014Assignee: Hitachi Construction Machinery Co., Ltd.Inventors: Katsumi Tamura, Kazumasa Horii, Knud Jensen Meldgaard

Patent number: 8167012Abstract: The foundation includes an assembly of wooden components which interconnect to form an enclosed rectangular configuration for supporting a mattress. At each corner of the assembly are two posts which are interconnected by dowels or by a tongue and groove. The dowels and the mouths of the openings in which they are accommodated are bevelled for facilitating the insertion of the dowels into the openings should they be misaligned. The tongues and grooves are also bevelled for the same reason. The wooden components are subject to compressive forces and to a heat treatment before being assembled into the foundation.Type: GrantFiled: March 31, 2010Date of Patent: May 1, 2012Assignee: Pine Ridge Forest Products, Inc.Inventors: Shawn Hicks, Knud Jensen

Publication number: 20060156914Abstract: The invention concerns a hydraulic control (1) with a supply connection arrangement (7) having a high-pressure connection (P) and a low-pressure connection (T), a working connection arrangement having two working connections (A, B) connectable with a consumer, a control valve (8) with a valve element (9) between the supply connection arrangement and the working connection arrangement and a compensation valve (11), which is located between the high-pressure connection (P) and the control valve (8) and is acted upon in the closing direction by a pressure between the compensation valve (11) and the control valve (8). It is endeavoured to ensure the most favourable energy consumption possible. For this purpose, in the opening direction the compensation valve (11) is acted upon by a pressure of a selection device (29, 30, 30?, 38), which optionally supplies the compensation valve (11) with a pressure control pressure or a flow control pressure.Type: ApplicationFiled: December 21, 2005Publication date: July 20, 2006Applicant: Sauer-Danfoss ApsInventors: Carl Dixen, Knud Jensen, Steen Slot, Svend Giversen, Svend Thomsen, Smari Johannsson

Publication number: 20050257519Abstract: The invention concerns a hydraulic valve arrangement (1) with a control valve module (2) comprising a supply connection arrangement with a high-pressure connection (P) and a low-pressure connection (T) and a working connection arrangement with two working connections (A, B) as well as a control valve (3) between the supply connection arrangement and the working connection arrangement. It is endeavoured to improve the control behaviour of the valve arrangement. For this purpose, it is ensured that the control valve module (2) has a return compensation valve (15, 16) between the control valve (3) and at least one working connection (A, B).Type: ApplicationFiled: May 11, 2005Publication date: November 24, 2005Applicant: Sauer-Danfoss ApSInventors: Knud Jensen, Carl Dixen

Patent number: 4225435Abstract: The invention concerns a blocking device for obstructing the opening of an inlet pipe in a sewer manhole, so that rats and like rodents are restrained. The blocking device comprises a ball or pear-shaped floatable blocking body for automatic blocking of the pipe opening by gravity when there is no flow of waste material into the manhole, said blocking body being pivotally suspended from a supporting means which by means of a tightening member is secured above the pipe opening by being wedged between opposite wall portions of the manhole. The blocking device also has a stopping means for limiting the penetration depth of said blocking body in the inlet pipe.Type: GrantFiled: May 8, 1978Date of Patent: September 30, 1980Inventor: Knud Jensen
