Appl. No.:

09/965990

Inventors:

Jerry Carlson - Spencer IA, US
James Casey - Spencer IA, US

Assignee:

EATON CORPORATION - Cleveland OH

International Classification:

F01M001/10

US Classification:

074/60600R

Abstract:

A hydrostatic transmission having a fluid pump (), and a fluid motor () disposed in a housing () which is in fluid communication with a source (C) of low pressure fluid. The housing () defines a recessed area () and disposed therein is a piece of filter material (), the recessed area intersecting the flow path through the transmission at a location between the low pressure source (C) and an inlet () to the pump (). The flow area of the recessed area is substantially greater than that of the flow path through the transmission. The piece of filter material () is attached directly within the recessed area () in a manner sufficient to maintain the filter material therein during flow through the flow path. The invention provides substantial filter capacity without adding to the overall size or cost of any of the transmission components.

International Classification:

F15D 1/00

US Classification:

13756501, 137613

Abstract:

A valve is provided including a first valve member and a second valve member. The first valve member includes a first step and a first orifice adjacent the first step. The second valve member includes a second step and a second orifice adjacent the second step. The second valve member is movable relative to the first valve member between an open position, in which the first orifice is fluidly connected the second orifice, and a closed position, in which the first orifice is substantially fluidly disconnected from the second orifice. The first and second steps are fluidly connected to the second orifice and substantially fluidly disconnected from the first orifice when the second valve member is in the closed position, and the first and second steps are fluidly connected to the first and second orifices when the second valve member is in the open position.
