An oil control valve for controlling a cam phaser includes a valve housing, a recirculation housing, a spool guide, a spool, a first and second recirculation valve, and a one-way inlet valve. The valve housing has a pressure inlet port, a first bore having a first inner surface, a first port, and a second port. The recirculation housing has a first slot, a second slot, a second bore having a second inner surface, and a first outer surface. A first recirculation valve is disposed in the first slot of the recirculation housing. A second recirculation valve is disposed in the second slot of the recirculation housing. The one-way inlet valve disposed in the pressure inlet port. The recirculation housing and spool are each slidingly disposed to have a first, second, and third modes.

Oil control valve for cam phaser

A cam follower assembly having a plastic guide body and a cam follower having two opposing roller shaft ends is provided. The single piece guide body includes a pair of grooved members. Each of the grooved members include an interior surface defining an elongated guide groove having a recessed surface. The elongated guide grooves are facing and aligned with each other. The cam follower is disposed between the pair of grooved member such that one of the roller shaft ends is received in one guide groove and the opposite roller shaft end is received in the other of the guide groove. The roller shaft ends are slidable in a reciprocal axial direction within the elongated guide grooves and retained between the recessed surfaces. The plastic guide body may be injection molded from a nylon material having glass fibers.

Cam follower and guide assembly

A mixing apparatus and system includes a hub, a plurality of blades, and a respective hinge for each blade to pivotally secure each blade to the hub. Each hinge including a lock having a tab and a detent to secure the respective blade in an operating conformation.

Mixer assembly apparatus and method

A control valve includes a valve housing extending along a longitudinal axis. The valve housing defines an inlet port, a first outlet port, and a second outlet port. In addition, the control valve includes a spool guide disposed inside the valve housing and a flow guide belt disposed around the spool guide. The flow guide belt is disposed inside the valve housing. The control valve further includes a spool movably disposed in the spool guide. The spool can move relative to the valve housing along the longitudinal axis between a first spool position and a second spool position. The first outlet port is in fluid communication with the inlet port when spool is disposed in the first spool position.

Mixer attachment assembly apparatus and method

A lifter oil manifold assembly for variable actuation of engine valves having first (top) and second (valve) plates having portions of oil control and oil exhaust passages formed therein. The assembly further includes a carrier member having an oil supply passage integrated thereby separating the oil supply path from the oil control and oil exhaust path. Further, the assembly includes towers for receiving and positioning the electro-magnetic oil control valves used to control oil flow in the assembly. The towers are molded separate from the carrier and are held in place by the valve plate or are molded integral with the carrier. In another aspect of the invention, oil control valve retention springs are molded integral with either the tower or the oil control valve. In a further aspect of the invention, a combined polymer restrictor/strainer in the oil circuit replaces a prior art metal die-cast restrictor.

Lifter oil manifold assembly for variable activation and deactivation of valves in an internal combustion engine

A roller finger follower assembly for variably activating a valve in an internal combustion engine includes at least one vertical recessed channel formed inside an outer arm and a shaft. The channel includes a machined upper surface closing the channel. The shaft engages with the recessed channel, the shaft reciprocates within the recessed channel, and the upper surface stops an upward movement of the shaft.

Inner arm stop for a switchable rocker arm

A deactivating hydraulic valve mechanism includes a hydraulic element assembly disposed within cup within a pin housing slidably disposed within a bore in a body. A transverse bore in the pin housing contains selectively-retractable locking pins that engage a locking feature in the body to selectively lock together the body and the pin housing. A lost motion spring is disposed in a vented annular chamber between the body and the pin housing. An oil passage from an engine gallery to the hydraulic element assembly includes an axial component formed in the cup and bypasses the lost motion chamber. A ring holds the lifter assembly together and also sets mechanical lash. The ring may combine a standard-thickness ring and a shim selected to provided a predetermined amount of mechanical lash in the assembled mechanism to ensure facile engagement and disengagement of the locking pins in the body.

A transverse bore in the pin housing contains selectively-retractable locking pins that engage a groove in the body to selectively lock together the body and the pin housing.

An oil passage from an engine gallery to the hydraulic element assembly includes an axial component and bypasses the lost motion chamber.

A system for selectively switching the action of a valve in an internal combustion engine includes a roller finger follower having a frame and a disengageable roller. A two-part axial pin for the roller axle is spring-loaded to urge the pin axially of the roller axle to disengage the first part of the pin from the follower frame and simultaneously disengage the second part of the pin from the roller axle. Thus the roller becomes detached from the frame and the follower cannot actuate its designated valve. The roller and pins are retained within the frame by at least one torsion spring. The pins may be controllably reinserted into the sides of the roller and frame to reconnect the roller to the frame by any of various electromechanical and/or hydraulic means. When used in conjunction with a camshaft having high lift and low lift cam lobes, the deactivated follower will then actuate its designated valve according to the profile of the low lift lobes, which may be a no lift profile.

Actuation mechanism for mode-switching roller finger follower

A variable camshaft phaser (VCP) has lash take up drive piston assemblies with inner and outer helical splines for phase changing and return springs mounted in pockets in the pistons to shorten overall length for a compact unit and also relieve lash take-up friction on the piston return strokes. Numerous other features are included. A three-way feed-discharge valve limits oil flow to that necessary to operate the drive pistons for phasing.

Compact camshaft phasing drive

A camshaft has, for each valve lifter, a high lift cam between two low lift cams, the high lift cam fitting within the envelope of the low lift cams. The lifter comprises an outer tappet elongated in the direction of the camshaft and slidably mounted in an elongated bore in a cam carrier. The outer tappet is contacted by both low lift cams and operates two valves simultaneously. An elongated bore extending transverse of the outer tappet carries an elongated inner tappet which is contacted by the high lift cam. A hydraulically actuated locking mechanism couples the tappets for movement together for high lift operation and unlocks for low lift operation to allow the inner tappet to idle in the outer tappet.
