US Patent:
8074558, Dec 13, 2011
Filed:
Apr 30, 2008
Appl. No.:
12/149327
Inventors:
Michael L. Knussman - East Peoria IL, US
William Edward Frank - Peoria IL, US
Cory Lynn Fisher - Bradford IL, US
Assignee:
Caterpillar Inc. - Peoria IL
International Classification:
F04B 49/12
F04B 1/12
US Classification:
92 122
Abstract:
An axial piston device for use with a hydraulic system is disclosed. The axial piston device may have a body defining at least one bore and having a central axis, a pump piston disposed within the at least one bore to at least partially define a pumping chamber, and a tiltable plate biased into engagement with the pump piston. The axial piston device may also have an actuator configured to selective tilt the plate relative to the central axis of the body to thereby vary a displacement of the pump piston within the at least one bore. The actuator may have a control piston operatively connected to move the tiltable plate, a rotary motor, and a valve driven by the rotary motor to control fluid communication between the control piston and a source of pressurized fluid to move the control piston.

Meterless Hydraulic System Having Restricted Primary Makeup

US Patent:
20130047592, Feb 28, 2013
Filed:
Aug 31, 2011
Appl. No.:
13/222945
Inventors:
Patrick Opdenbosch - Peoria IL, US
Michael L. Knussman - Peoria IL, US
Joshua Dierking - Peoria IL, US
International Classification:
F15B 13/042
US Classification:
60327, 60459
Abstract:
A hydraulic system is disclosed. The hydraulic system may have a primary pump, a hydraulic actuator, and first and second passages fluidly connecting the primary pump to the hydraulic actuator in a closed-loop manner. The hydraulic system may also have a charge circuit, a makeup valve movable to selectively allow charge fluid from the charge circuit to enter the first or second passages, and at least one restricted pilot passage configured to direct pilot fluid to the makeup valve to move the makeup valve and allow the charge fluid into the first and second passages.

Meterless Hydraulic System Having Load-Holding Bypass

US Patent:
20130047599, Feb 28, 2013
Filed:
Aug 31, 2011
Appl. No.:
13/222990
Inventors:
Patrick OPDENBOSCH - Peoria IL, US
Michael L. Knussman - East Peoria IL, US
Joshua Dierking - Peoria IL, US
International Classification:
F16H 61/4035
F16D 31/02
F15B 13/01
F16K 17/04
F16K 15/00
US Classification:
60464, 251337, 137516, 60468
Abstract:
A hydraulic system is disclosed. The hydraulic system may have a pump, a hydraulic actuator, and first and second passages fluidly connecting the pump to the hydraulic actuator in a closed-loop. The hydraulic system may also have a control valve, and a load-holding valve configured to selectively lock movement of the hydraulic actuator. The load-holding valve may include a valve block at least partially defining a pump passage, an actuator passage, a control passage, a restricted passage connecting the actuator passage and the control passage, and a bypass passage connecting the actuator passage and the control passage. The load-holding valve may also include a valve element movable between a first position at which flow between the pump and the hydraulic actuator is blocked, and a second position at which fluid is allowed to flow between the pump and the hydraulic actuator, the valve element being spring-biased toward the first position.

Meterless Hydraulic System Having Displacement Control Valve

US Patent:
20130048117, Feb 28, 2013
Filed:
Aug 31, 2011
Appl. No.:
13/222895
Inventors:
Patrick OPDENBOSCH - Peoria IL, US
Michael L. KNUSSMAN - East Peoria IL, US
Joshua DIERKING - Peoria IL, US
International Classification:
F15C 3/00
F16K 11/20
US Classification:
13756501, 137597
Abstract:
A hydraulic system is disclosed. The hydraulic system may have a pump, a tank, a displacement actuator having first and second chambers, a regeneration valve, and a load-holding valve. The hydraulic system may also have a displacement control valve including a valve element, and a stationary cage portion at least partially forming a high-pressure passage fluidly connecting the pump and valve element, a low-pressure passage fluidly connecting the valve element and tank, a first displacement actuator passage fluidly connecting the valve element and first chamber, a second displacement actuator passage fluidly connecting the valve element and second chamber, a load-holding control passage fluidly connecting the valve element and load-holding valve, and a regeneration control passage fluidly connecting the valve element and regeneration valve. The displacement control valve may also include a movable cage portion that is movable to selectively restrict fluid flow through only the first and second displacement actuator passages.
