Publication number: 20210190076Abstract: In an adjustable coolant pump for delivering a coolant for a combustion engine, a delivery flow of the coolant can be limited by a regulating slide which is actuated by a hydraulic actuator in a hydraulic control loop, wherein the hydraulic control loop is supplied with the coolant from the delivery flow, and includes an axial piston pump and a proportional valve for generation and adjustment of a pressure on the hydraulic actuator. A sliding shoe, which is arranged on an intake side of the axial piston pump, surrounds an inlet of the axial piston pump, and a filter disk for filtering the coolant prior to entry into the hydraulic control loop is in sliding contact with the sliding shoe so that coolant from the pump chamber is sucked into the axial piston pump through the filter disk and the sliding shoe, while a rotational movement of the filter disk is transformed into a stroke movement of the axial piston pump. The filter disk consists of a ceramic material.Type: ApplicationFiled: March 7, 2019Publication date: June 24, 2021Inventor: Toni STEINER

Patent number: 11002281Abstract: A mechanically driven coolant pump having a controllable delivery rate for a main delivery circuit from a first outlet and for a secondary delivery circuit from a second outlet of the coolant pump. The coolant pump comprising a hydraulic control circuit which is derived from the coolant pump and has an input-side auxiliary pump, an output-side proportional valve, and a regulating slide for limiting the flow of the main delivery circuit. A cylindrical portion of the regulating slide can be axially displaced in the pump chamber in order to radially shield the pump impeller by means of a pressure in the hydraulic control circuit counter to a restoring force. A regulating valve is connected to the hydraulic control circuit to limit the flow of the secondary delivery circuit, wherein actuations of the regulating slide and of the regulating valve are associated with pressure ranges in the hydraulic control circuit.Type: GrantFiled: July 12, 2018Date of Patent: May 11, 2021Assignee: NIDEC GPM GMBHInventors: Franz Pawellek, Toni Steiner

Patent number: 9140379Abstract: An apparatus for activation of a control valve is configurable as a slide, ball valve, rotary slide, poppet valve, or the like, and controls or regulates pressure-impacted media, for example, regulating the coolant volume stream of an internal combustion engine. A push piston linearly displaceable in a piston guide rigidly disposed on the flow housing, with an activation joint, is fastened onto the flow housing. A connecting rod is disposed in the activation joint. A push joint is disposed at the push piston end that lies opposite the activation joint, in which push joint the activation element of a control valve is displaceably and/or rotatably disposed. A reset spring is disposed adjacent to the push joint and acts on the push piston, in the direction of its longitudinal axis, so that the push piston always lies against the connecting rod without play, with the activation joint.Type: GrantFiled: January 7, 2012Date of Patent: September 22, 2015Assignee: NIDEC GPM GmbHInventors: Andreas Schmidt, Toni Steiner

Publication number: 20130081720Abstract: The invention relates to a lubricant valve for oil pumps of internal combustion engines, in order to supply the bearings and sliding surfaces of the engines with lubricant in an optimum manner in order to reduce the wear. The invention is based on the problem of developing a lubricant valve for oil pumps of internal combustion engines, which lubricant valve combines, in particular, the functions of a cold-start valve and those of a control valve within itself with a minimum amount of installation space and is constructed in such a way that it is insensitive with respect to the wear debris and/or foundry sand which is entrained by the lubricant, in the process makes high throughflow quantities possible, in addition is of inexpensive construction in terms of production and assembly technology and can be produced inexpensively, and, moreover, always operates robustly, reliably and insusceptible to disruptions, even under extreme use conditions.Type: ApplicationFiled: April 20, 2011Publication date: April 4, 2013Applicant: GERAETE- UND PUMPENBAU GMBH DR.
