摘要： A hydraulic lash assembly (HLA) for use in a valvetrain. The HLA preferably includes a first arm configured to transition a valve between a closed orientation and an open orientation. The first arm can include an engagement surface to receive a driving force from a timing member and to cause the valve to transition to the open orientation for a predetermined period. The HLA further preferably includes a second arm to receive a holding force from an actuator and a pivot section to couple to the first arm and displace the first arm based on the holding force from the actuator. Preferably, the first arm and the second arm form a lever arrangement whereby the pivot section of the second arm underlies and supports the first arm and allows for rotational movement of the first arm that is independent from the second arm.

摘要： A spool valve for controlling the flow of a fluid into a reciprocating piston cylinder. A spool is slideably inserted into an outer casing, the spool valve having a first and a second non-waisted end portions and having a waisted middle portion. The casing has an intake port and output port for fluids entering and exiting the casing. A first non-waisted end portion covers the intake port during a first valve-closed event as the spool slides in one direction within the casing. The waisted middle portion is sufficiently wide to uncover both the intake port and the output port during a valve-open event as the spool slides in one direction within the casing. A second non-waisted end portion covers the output port during a second valve-closed event as the spool slides in the same one direction within the casing.

摘要： A valve system that includes a housing defining an intake port, a cylinder port and a valve bore; wherein the intake port defining a valve seat portion at an interface between the intake port and the cylinder port. The valve system also includes a valve to control fluid communication between the intake port and the cylinder port. The valve includes a valve stem disposed within the valve bore and extending into the cylinder port and extending out of the housing, the valve stem having an open face exposed to atmospheric pressure and a valve head coupled to the valve stem comprising a first face and an opposing second face. A diameter of the valve stem is selected to control a closing force on the first face of the valve head.

摘要： A testing rig and method of testing a bearing with the rig, wherein the rig includes a bearing housing, wherein said bearing housing includes an opening and a drive shaft extending into said opening, wherein the drive shaft is rotatable around a bearing axis. The testing rig also includes a vertical actuator mounted on the bearing housing for applying a vertical load to the bearing housing and a horizontal actuator mounted on the bearing housing for applying a horizontal load to the bearing housing. In addition, the testing rig includes a first misalignment actuator coupled to the first actuator for applying a first misalignment load to the bearing housing and a second misalignment actuator coupled to the bearing housing for applying a second misalignment load to the bearing housing.
